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%!

1080p Hidden Camera Spy Glasses

Due to popular demand, I've finally reviewed some 1080p 'Spy' Camera Glasses.

If you are thinking I should have instead reviewed Google Glass or Liquid Image's camera Goggles - remember that the only reason that that this video was made because people asked to see my take on some of the cheap Chinese 'spy glasses' cluttering up that's what this video is about. I also decided that I should attempt to find the most discreet 1080p glasses available. The kind of spectacles I could wear anywhere without drawing attention to myself. Watch the video below to see how I got on.

You can try your luck at finding some spy glasses yourself on ebay by Clicking Here, but I have a feeling that any money spent on the current selection will likely be money wasted.

I'll probably take a look into camera glasses again in a year or so if the technology has improved, because the idea of hands-free discreet head-mounted recording is an appealing one. Personally though these kind of glasses will never be any use to me because I wear prescription lenses and I can only wear glasses like this for short periods before I get a headache due to eye-strain.

Just a bit of behind the scenes info. The final shot was supposed to have a glasses POV aspect to it too. Unfortunately the SD card was destroyed during the I'd suggest you don't try and copy this at home. Before I shot the scene I tried to swap out my decent SD card with a cheaper one - but the cheap one slid inside the arm of the camera and vanished... so I took the risk of shooting with the decent card. Losing a £15 memory card is not the end of the world and it's just part of the costs asscociated in trying to make a dodgy product into an interesting video.

Good video btw,as always,chears my man,waiting to hear (watch sth ) from you soon..probably again in a week or so,


May 12, 2014 | Unregistered Commentergeorge

Thanks for review. Was interested in buying precisely these glasses
Now I know I won't do this.

May 12, 2014 | Unregistered CommenterStan

Thanks, looking forward to watching it, a nice Monday evening treat ;-) First comment though, they don't appear to be terribly discrete with their holes on both sides on the front ? Anyway, let's get the video low down !

May 12, 2014 | Unregistered Commenterwebvan

Thanks again for another great review. It's the best way to start the week, laughing out loud with your antics.

I also had eyed them out to wear them inside my helmet as a motorbike "dash cam" but, alas, you confirmed my suspicions. After such less-than-stellar review and the application of the Toyota of Doom I'll stick to my trusted Mobius.

Keep up the great work.

There are several situations where these could be very useful:
1. Sales Manager with salesman on a call. All sound (hi-fi quality immaterial) and customer body language (very material) recorded. Perfect for a de-brief
2. Recording politicians on the doorstep asking for your vote
3. Crap retail customer service
4. Recording politicians on the doorstep asking for your vote
5. Recording Estate Agents
6. Recording politicians on the doorstep asking for your vote

Please do not destroy the next sample - I can definitely put it to good use

Great review again :) From my experiences with sunglass videocameras I guessed how the review will end :D

I'm on my second sample of sunglass DVR. First was so terrible it corrupted almost all videoclips I made with it, it had 640x480 video with 30fps, terrible sound & eventually it got my nerves that much I destroyed it by smashing it on my bike steering bar.

Second one I still have and it's with 1280x960 video, most likely just doubled from 640x480, very slow frame rate just like in your review, weak sound, white balance reacts too heavily on sun & shadow, audio and video aren't in sync, etc. Have been very tempted to destroy this one as well :D

I begin to think there is no decent sunglass videocamera made yet, at least in this price range. It would definetely need wide angle lens, true 30fps with high shutter speed, 1080p resolution, good microphone and long lasting battery.

"Monkey head butting a keyboard" = classic line!

Did I spy a round dashcam on your windshield (windscreen)? Reviewing a new model?

May 12, 2014 | Unregistered CommenterChris

Finish guy, there are some decent ones out there, the problem is that they are anything but cheap.

You seem to be very interested in the subject so try this: I don't remember neither the brand nor the episode in which they were featured but if you search through the archives of The Giz Wiz Show podcast ( you'll find one about three years ago where they reviewed a 1080p model. It shows up great footage. In a boat nonetheless!

If I recall correctly they were around $300 at the time and not exactly the utmost covert.

The show's main page is here: and I know there is a searchable database somewhere.

You're welcome. ;o)

Finish guy, that is what you want:

I agree with Dashing Along, Pivothead is the way to go although many people spot the camera quickly.. Btw I liked the final shot of your excellent review. Thanks again Mat.

May 13, 2014 | Unregistered Commenteraviva

Here's a video that shows what it can do.
He talks too much though :-)

May 13, 2014 | Unregistered Commenteraviva

Ha ha awesome Matt

Being a real spy in Canada, I just stick to Lawmate products and the amazing 808 #26 key fob. Problem with glasses is that ya have to look at the subject, and that will end in tears always.

May 13, 2014 | Unregistered CommenterPaul

Thank you for this review. I have been very curious regarding these devices. I appreciate you letting us know that you don't plan to review these devices in the future. I was hoping to get your review of a Pivothead device. But I will look elsewhere... or maybe I will do my own review. That would be crazy.

Loved the review.
And as always - Thanks for letting us watch.

May 14, 2014 | Unregistered CommenterMatt

Oh dear... you killed a MicroSD card as well!!
Collateral Damage?

Love your work.
Keep the reviews coming.

May 16, 2014 | Unregistered CommenterMarko

Now, if the Mobius makers could re-work their camera into the shape of glasses, I'd certainly be interested. I bought some real cheap spy glasses many years ago just for the novelty but they were terrible, looked bad, not nice to wear, produced bad quality video, they've been sitting in the case ever since.

May 17, 2014 | Unregistered CommenterHaku

Matt I don't think that guy in the street spotted you where wearing spy glasses, I think he recognised you... after all you are famous!

May 18, 2014 | Unregistered Commenterdrozd

"..chimp hitting it's head against a keyboard.." Classic! Great review.

May 19, 2014 | Unregistered Commenterjm

I bought something quite similar for cycling.
Absolute rubbish, with similar results that Mr. Techmoan has shown here.

May 21, 2014 | Unregistered CommenterSimon

Thanks for the again very useful review. I have purchased the fake Oakley sunglasses. They are 720P. Apart from the inevitably thick legs the stealth is very good and the picture quality is quite good.

May 21, 2014 | Unregistered CommenterJörgen Baumwolle

I was thinking 720p might give better results as that requires less horsepower, what's the reference of these "oakley" looking glasses and where did you get them? Thanks!

May 21, 2014 | Unregistered Commenterwebvan

I bought them from this vendor:

May 21, 2014 | Unregistered CommenterJörgen Baumwolle

Jörgen Baumwolle, can you share samples from your glasses in daylight and dark times? And how long do the work on battery?

May 21, 2014 | Unregistered CommenterStan

..... ooo, we went INSIDE Woo Sang!! :-)

May 22, 2014 | Unregistered CommenterEddie

@ techmoan your memory card may not be destroyed- HP card formatter can restore corrupted and alleged unreadable cards.

May 22, 2014 | Unregistered CommenterDAN

Video from those "720p oakley" glasses from seller:

May 22, 2014 | Unregistered CommenterStan

@Dan. I may try that out because I've still got the card...however it's not mounting at the moment, so it looks like it's probably had it.

May 22, 2014 | Registered CommenterTechmoan

Hi, can anyone recommend a good high quality spy watch cam? Can't seem to find much in the way of reviews comparing different models and not sure where to post. Many thanks

May 22, 2014 | Unregistered Commenterjames

@Stan, the battery lasts about an hour, Youtube has several samples available when you search for 'fake oakley sunglasses camera'

@james, search ebay for 720P IR watchcam with SD/TF card reader.

May 23, 2014 | Unregistered CommenterJörgen Baumwolle

You could have tried dropping them fro a great height, whilst they were recording...Instead of running over them. The footage would have been interesting!

May 26, 2014 | Unregistered CommenterAbz

Techmoan, let me say that I am a latecomer to / devotee of, your excellent reviews. I reckon that most TV voiceover [er] s would benefit from a study of your clear, careful, diction and presentation.
Pleasantries completed, I feel that this one is somewhat harsh, I cannot agree that the video or sound was 'terrible'.
The only fair complaint I would think, is that head movement is a problem, and would be apparent in any situation without stabilisation.
When the glasses were worn by your passenger.....approaching Knutsford I believe......I could see no reason for complaint.
All in all, I would class these glasses as inexpensive. Miniature sound and vision recording for "around £30.00" come on, perhaps we are becoming spoiled by today's technology?

If you would like really to review some expensive non-performing junk, with equally rubbishy documentation, go to Response Electronics Ltd. and waste almost £100.00 on their 'Wireless Twin Door Entry and {non-working} DECT Telephone System", where you will find a REALLY miniaturised and gobbledegook Instruction Manual!.....You'll find them ensconced behind Amazon / Securicare etc.].

Regards, Ian Colley.
