What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Xdreme Camera Review

Does the Xdreme (Blue) improve upon the Crocolis (Red)?I'm trying to catch up on my reviews at the moment, so if in my rush I've forgotten to include something in this video, let me know and I'll try and cover it up in a future mop-up video when I've got sufficient time.

One thing that I did intend to mention was the size of video files created by this camera. People with good math skills can probably work it out from the video bitrates, but for the rest of us I can confirm that in my tests 15min at 1920x1080 30fps took up 970MB of space. 

One thing I know that I didn't test is motion activation. I know that some people are interested in this feature, but I really can't figure out how to demonstrate it in a meaningful way. Clearly, when the camera in this mode if I wave my hand in front of the lens it starts recording...but is that all people really want to know, because it all seems rather rudimentary to me. Let me know.

If you want to download a few short samples of clips from the camera Here is a folder on pcloud.

I am trying out affiliated links, so here is my link to the Xdreme camera on Chinavasion. Remember though that in the UK, you will likely get stung with customs and 'handling' fees when you import from China, so factor that into your budget.

Great Review as all that you do seem top be. I purchased a Crocolis based upon a review that you did. Somewhere I lost it, I went back to China Vasion to get another and found that the Xtreme was acvailable. I immediatley checked and yes yoy had done a review so instant purchase based upon your review. I hope you keep finding the time to do such great reviews

I compared the Crocolis Extreme cam with the Gopro Hero 2 at night, and the Gopro Hero 2 is way better. Check the video clip here

October 7, 2012 | Unregistered CommenterJoburgTraffic

Well fancy that joburg Traffic - you've found a camera that costs (with the rear LCD screen in place) near-as four times the price of the Extreme cam and it performs better in the dark. Well I'll be blowed. And don't forget that the Extreme cam is at least a stop more sensitive in the 1080 /25 mode than in the 720p mode.

@ JoburgTraffic

Aehrm.... But this is not the Crocolis camera, but the improved Exdreme... :)

@ JoburgTraffic

Aehrm.... But this is not the Crocolis camera, but the improved Xdreme... :)

October 11, 2012 | Unregistered Commenterjenshenrik

I don't think it's 'improved' by much, and it's the same price. The Extreme cam allows you to fit a WD40 lens cap to protect the camera's vulnerable plastic front element, but the 'improved' Exdreme doesn't allow this.

October 11, 2012 | Unregistered Commentertom hardwick

@JoburgTraffic and Tom Hardwick

I have found that the best play back and colour representation for movies recorded on the Xdreme (not the Crocolis) camera is achieved with Quick Time (seems to have the best codec).
I have recorded on my Xdreme, on a friends GoPro and on a Drift HD and in "full light" conditions, colour, motion stabilisation and sharpness is similar on all cameras (in fact the Xdreme and GoPro were the closest). In "low light" conditions (4:30am on an August morning in Gauteng), the Xdreme and GoPro were the same in terms of movie capture - the GoPro loked a little more "fish eyed". All movies were recorded in 1080p/30 and the one tip I can provide is to ensure that all cameras are correctly set for the previling light conditions.

I've been korresponding with Chinavasion, as the locking clip is broken AGAIN!

They offer 1 year warranty, but the warranty in China seems to be an other thing in Chinese terms than in my European terms.

In stead of replacing the clip, they grab the chance of making some money here, now offering the costumers to BUY a new clip.

The clip costs $4,28 plus freight and can be bought here:

I certainly hope, they did improve the "new" clip, by increasing the distance between the two pins by approx. 1 mm.
I did as, but have not received any answer from Chinavasion.

I really hope, this was good news for all of you with broken cameras - Including Oz :)

G'day jenshenrik

My last communication with Chinavasion was on Sept 28. They were unable to reproduce the issue with random stoppages. I explained how I reproduced the error and they indicated that more testing was required at their end. I have not heard any news since then...


October 19, 2012 | Unregistered CommenterOz

Got my parcel yesterday.
Lucky me, I bought two sets. Today the first one was broken on the exact place as the first two ones...

What a shame.

There is extremely little information about attatching the Xdreme HD to a helmet (skiing). Could you tell me a bit more about This issue?
Your reviews are super by the way.

November 20, 2012 | Unregistered CommenterRombout

In my opinion the Xdreme is too large to attach to a helmet. You can do it though. I thought I did a bit about this in the video, but I haven't viewed it recently. Have a look at my Crocolis Extreme Cam video too as I'm pretty sure I covered it in that one. You'll find it on my YouTube channel.

November 20, 2012 | Registered CommenterTechmoan

I recently did a 1500km motorcycle trip around North Eastern South Africa And Western Swaziland. Approx. 900km of the trip was done off road. During the trip I had my Exdreme mounted on my helmet through the use of the universal mount attached to my goggles. Recorded in 1080p / 30 and the footage is brilliant.

November 20, 2012 | Unregistered CommenterGary

YOU, sir do an amazing job. I have watched as much as I possibly can. I have a blog also and I know its a labor of love. I like seeing other cameras that seem to always be just what I'm looking for. Not mass advertised, but decent quality. I wouldn't own a GOPRO!

I can do way more faster with my Kodak Playsports. But at the same time, are interested in the Extreme or Crocolis.


December 30, 2012 | Unregistered CommenterCapt Dave Sipler

Good day. Just 1 question. When you flip the camera upside down, does the time and date display also flip, or will the time and date then be displayed upside down when you watch the video?


January 19, 2013 | Unregistered CommenterJT

The time and date flip too...the orientation sensor ensures everything looks normal, either way up.

January 19, 2013 | Registered CommenterTechmoan

Hi Techmoan
I will not thank you for this ridiculousely funny AND detailled video review.
Just wanted to share with you and everybody who own that cam the best setting I've found regarding color rendering:

720P 60
White balance: Cloudy
Contrast: Hard
Sharpness: Standard
Iso: 100
AE: +0.7

I tried to reproduce the white of the snow whe currently have

Hope it helps !


January 19, 2013 | Unregistered CommenterSeb_la

Thanks four your reviews, I m planing to get one of these myself !
Just one question : does it charge while in use? Or it depends only on the batery like the Contour cams? I could also use it as a dashcar camera/ car dvr plugged in the car cig lighter and on my byke with a 5000mah battery pack. Will it work with the battery removed but plugged in the car at 12/24v?
About sound quality and changing the lens : there s a video on youtube of how to do that, but it ain t that easy if you ask me. Stil the images with the new lens seem sharper and the colours nicer, plus no fisheye effect. About the sound, it seems there is something covering the mike for waterproof. Make a hole in there and you should ger better sound but you won t dive with it anymore!
Greetings from Spain & Romania and thanks a lot Techmoan !

Thank you for your review. I have bought the xdreme cam based on your review.

But i have one issue with it. When mounted in the car, it records a rattel sound, and when i am shacking it i can also hear the rattel. I'm guessing it's from that orientation sensor. Dose anyone has this issue with it ? Has someone tried to get the orientation sensor out of the camera ?

Thank you!

January 30, 2013 | Unregistered CommenterAndrei

Hi Techmoan,

I like your reviews, you do a great job. I bought this camera based mostly on your review.
I'm very happy with it. It has excellent video quality and is very versatile, even as a car DVR. The sound is a little disappointing. The internal mike is as expected for a watertight camera and the supplied external mike is only good without wind interference which makes it useless on the motorbike at speeds above 40kmh. I've ordered another mike which was hard to find being a 2.5mm jack so hopefully I'll see an improvement.

Keep up the good work.

January 30, 2013 | Unregistered CommenterJohn D

--> Andrei... Yes, i have same issue fith sound. I took camera apart, and im pretty sure, the orientation sensor makes the noise, when camera shakes. Orientation sensor is placed in front part of camera on plate with lens and sensor. It looks kite small sqare chip with white dot on it. I cowered it by melting glue to try reduce the noise, but it didnt hel much :-/

If u want to improve sound, u can make external mic. or just remove rubber covet on mic hole, placed under bottom plastic plate, holding by few small screws.

I also remowed the lens holding by 2 screws, then place it back, but dont screw it corectly on place... it was about 1 mm far away from plate with sensor. It cause, the camera was focused for distance about 3 - 10 cm an makes realy sharp macro photos :-)
Then i screwed lens to touch the plate witw sensor as originaly before. Its ok now, but i thing, by placing lens about 0,1 - 0,2 mm away from sensor, can make sharper pictures... will try it soon ;-)
Lens is in focusing screw, but its glued well :-/

Sorry for my english :-D

what sd card do you recomend for the Xdreme?

February 26, 2013 | Unregistered Commentergoogleboy

I always suggest using a Class 10 card from a manufacturer that you recognise from a shop that you trust.

Any make you trust should do the same job, Samsung, Kingston, Sandisk, etc...just watch out for copies from dodgy sellers on eBay and Amazon-marketplace.

February 26, 2013 | Registered CommenterTechmoan

Just to follow up:

Regarding a cap/lense cover: I found out, that one can modify the cap of an ordinary water bottle.

Take a look at the images via this link.

The link also contains images of the weak locking clip.

We haven´t got any feed back from Oz yet? :)

March 29, 2013 | Unregistered Commenterjenshenrik

WOW: Some one went back to the drawing board!

Have ya seen your croc and extreme lately?

It's all NEW looking. 12/24/2013

On Ebay:

Or at least this is what it reminds me of.


December 25, 2013 | Unregistered CommenterCapt Dave "Jettywolf"

That's interesting Dave, not interesting enough for me to buy one, but interesting all the same. I'd imagine the metal looking bits on this are really painted plastic. That fake metal/plastic stuff really needs a name...Pletal? Metastic?

December 25, 2013 | Registered CommenterTechmoan

Hello, I have bought this camera but notice that the recording goes from sharp to soft seemingly randomly, does anyone else notice this. I use 720/60, wondering if its hardware or software issue?



December 31, 2013 | Unregistered CommenterD

Once again excellent review Techmoan, thank you very much !!
I bought one (XDREME) after watching your review and ended up with malfunctioning camera and am sending it back but most probably will order another one.
The problem I had with the camera was actually weird. After filming, from the very beginning, the shots, or movies as the camera referred to them was INVALID and it used recovery motion. After using the recovery motion it only recovered minutes part of it which was very confusing.
I tried and used the default settings which did not help at all. I then used the record overwrite and set it 15 minutes and the camera then started recovering only the 15 minutes of recording, again very frustrating. So I decided to return the camera back to its suppliers and like I said I will most probably order another one in the hope that I will this time get a properly working camera.

February 21, 2014 | Unregistered CommenterBilly Turk

You mention that you where at loss when it came to meaning full test of the motion sensor test, why not try a bird feeder stuck to the out side of a window and the camera on is windscreen mount on the inside, see what visitors you get. Shirley in darkest parts on Manchester there must be a good looking bird willing to do some filming for a fee meal?

Keep up the good work ;)

March 2, 2014 | Unregistered CommenterAlex

I really appreciate your camera reviews, especially this one on the Xdreme camera. In this review you mentioned software control of zooming. What do you use for software? I know there's a ton of software available but do you recommend any particular one? Perhaps as future review subjects you could compare various software options.
