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%!

Gtech AirRam Battery Powered Vacuum Cleaner

After Christmas I had some Amazon vouchers to spend and this coincided with a I bought a vacuum cleaner. Here's a video I made about it.

If you want to get hold of one in the UK they are stocked by Costco but it might be easier getting one sent directly from the Manufacturer with free UK next day delivery. US viewers can get one at and of course it can also be found at Amazon in the UK or US.

I've been watching your vids (excellent thank you) on the Crocolis and SVC200 trying to make my mind up which one to get for a bit of sailing footage when I noticed your new test on the AirRam. We've bought a grand total of three of these now! One for home, one for the inlaws and one for a boat. They're absolutely bl**dy brilliant. We used to be in hospitality and have an arsenal of fancy vacuums which are all sitting gathering dust as these little Gtech's knock the spots off all of them. I do the bulk of our stairs with one just by using it sideways and working left to right, right to left over the treads. Way quick! One thing you didn't mention is if it's more convenient, you can charge the battery off the vacuum.

By the way, sound quality ignored, which camera would you favour?

January 29, 2014 | Unregistered CommenterJohny V

I did intend to mention that the battery could be charged away from the vacuum, but it slipped my mind during the edit...I'll add on an annotation. As far as cameras go though, I'd definitely recommend the SVC200.

Hi Mat, another interesting review, as always. I enjoyed your review of this little vacume.

I'm an ex Hoover employee, so I am bound to be a little sceptical of this one. That little dust chamber looks like it would need emptying almost every time you use it? The lid falling off each time you tilt it back, is a big design fault in my view, that should be tight and lockable, bearing in mind this item is new. What will it be like in a couple of years time of useage? I wonder.

The fact it's battery driven, does kind of limit it's life based on the battery life span, but I guess you can buy new ones at a cost.
I should point out, I've had the same vacume cleaner of 25 years ago and it's still picking up, the only thing I've had to change is the belt.

Interesting to branch out into other areas of tech though. I still think you should have your own TV show, where are the TV producers out there?!

Again, thanks for listening

Battery powered vacuum cleaner seems to be the best option. This looks good and hope this will work on all kind of floors.

January 30, 2014 | Unregistered Commentervacuum cleaner

Dam you mat, I have no interest in vacuum cleaners yet I'm still watching your review because they are pleasant to watch.
All your action camera you have and you did stick one to the side of the vacuum cleaner for the action scene (2min 40sec)

keep up the good work

January 30, 2014 | Unregistered Commenterjohngr

Can you mount a dashcam to this?


January 30, 2014 | Unregistered CommenterChris

yes you can but the usb power supply is all ways live so the camera wont start/stop automatlly.


January 30, 2014 | Unregistered Commenterjohngr

Another good review Mat.

I think even at £239 this is way too expensive. I appreciate that much of the manufacturing cost is probably down to the battery, but if you can get replacements for £65, then surely this price point is too high. Even a technologically much more advanced Dyson barely comes in this high.

Keep 'em coming.

Hi Matt,

Great to see your AirRam review, shame to see you had to fork out for one - my email to them telling them to send you one for review obviously fell on deaf ears!

I have being using ours now for around 8 months and must say am very pleased with its performance, it really does suck (meaning it's a good vacuum to any US readers!) and if you can get used to emptying the hopper every 20 minutes and don't try and use it on the stairs then it is very easy to live with.

I did try and used it on the stairs but whilst doing so something came loose inside and stated rattling around so didn't try that again. We also have an old Dyson so just have got used to doing the stairs with that so if you have stairs you will have to use an alternative for that. GTech replaced the AirRam within the week btw.

Our white and green version doesn't have the loose lid problem yours does for some reason - the lid pushes into the housing with a tight fit into the hopper and actually takes a bit of prising to get it off.

Battery life is easily enough to hoover a 10 room house and hallways with power to spare if fully charged when you start (45 minutes of vacuuming) and the cells show no loss of performance.

Must say its almost a joy to do the vacuuming now and makes lovely hoover lines on the carpet!

Shame we haven't been able to use the pc link as we are a Mac only household.

Great review as always.


January 30, 2014 | Unregistered CommenterNeilB

You really aren't missing anything with the USB connectivity...I never plan on using this again. I thought my lid might be loose...but with nothing to compare it against I had to point it out. I may well get the handheld version as well some time soon. I'm glad your machine is still working well, and thanks for trying to get me a free one...I think your email was the reason I looked into this machine in the first place, and ultimately the reason why I bought this one.

Replacing an idiotic Roomba with an Air Ram, exactly the same story here.
Back in November the manufacturer had a deal on (which they do every now and then) for £199 including delivery.
Since that delivery day I have never looked back. I had Dysons before and never had a problem with them but the Air Ram is far more convenient not having a cord.

I use it on the stairs with no issues. My lid isn't particularly loose and although it does need emptying more often, it does bale up the dust in neat blocks. It's also far less noisy than other vacuums.

I didn't know about the handheld Air Ram, that must be a new item on the site. I'll definitely consider replacing my frankly piss poor handheld Dyson. The battery in that thing is dire. They state 6 minutes maximum but real world performance varies between 3 minutes and 10 seconds.

HI : this query is about the Mobius 1080p action cam because I cannot seem to be able to email you from that page. Ive bought the Mobius as mentioned but cant instal msetup.exe file for some reason after many attempts.I presume this is needed to play back video. Can you please tell me how to take video.Ive read the instructions dozens of times but cant get the mobius to take video.Have emailed the seller but no reply.After switching on, camera goes into standby mode (yellow led on) I press the shutter button but nothing happens. I am tearing my hair out. Someone please help. thanks.

January 31, 2014 | Unregistered Commentervelvet lady

I'd really recommend watching my video about the Mobius camera, it gives a full demonstration of the functions. You don't need to install the msetup's entirely optional as it enables you to change settings...that the you probably won't need to change. I hope you've bought an SD card....but before you do anything the whole Mobius Review video from beginning to end.

January 31, 2014 | Registered CommenterTechmoan

Just a little heads up in case you are interested.
Even though I emailed them and asked for a discount for being a loyal customer and them offering me 10% discount (£14.90), today I received a Gtech leaflet through the post offering £20 if you go to and use promotional code TOOLS001. It's valid until the 30th of March.

February 3, 2014 | Unregistered Commenterevilution

Matt I had one delivered today is the same colour as yours and no amount of shaking upside down will the lid come adrift..if you need to compare mine to yours I am only round the corner from you

March 14, 2014 | Unregistered CommenterBigsyd

The better the quality of the vacuum, then the better the look of the carpeting on the stairs is going to be.

June 7, 2014 | Unregistered CommenterBejo

Interesting review.
I have a Hoover unplugged which is more or less the same only works off 30v battery. I am wondering how it would compare if you have come across one to be reviewed.
Also for the stairs I have a Black and Decker Dustbuster flexi portable with attachments which comes in at around £80. It is brilliant, has a powered rotating brush as well as crevice tool , soft brush for upholstery and stretchable hose, and is very powerful. A full charge will last about 30 minutes or so. It is very light in weight. The only negative is the dust chamber clogs quickly so you have to empty it more or less every time but otherwise it would be a good partner to this.
Still wondering though whether to swap my Hoover unplugged for this Air Ram.

June 14, 2014 | Unregistered CommenterWENDY HALL

Just ordered a Gtech. Didn't think about height adjustment considering we put new carpet in that is tall like the old shag carpet. Do you think this unit will work for this application.

August 22, 2014 | Unregistered CommenterMark S.

I have the Air Ram K9.
But unlike the ordinary Air Ram ,i am unable to connect it to the computer to change the speed/battery life.
Why can this NOT be done with the K9.

September 29, 2014 | Unregistered CommenterS Tovish

Don't be afraid if you don't have a perfect vacuum for your house. Just use i-Robot Roomba 650 for all corner of your house. Its amazing with its operational work.

January 6, 2015 | Unregistered CommenterElisa Wales

Love the upright Air Ram although lid falls off easily. So pleased to read reviews on Multi. Was about to buy but my elderly thumb joints won't constantly support the switch So come on Mr Grey, a new switch design is required

January 25, 2015 | Unregistered CommenterYvonne

I am on the verge of getting one of these, but not if they've still got that stupid plastic gear in. Have they sorted this achillies heel out yet ?

March 8, 2015 | Unregistered CommenterAnthony Hammond

Hope i will order one.

April 13, 2015 | Unregistered CommenterRazin

Battery powered vacuum cleaner is really good. there is no need to rely on electricity for work.

July 12, 2015 | Unregistered Commenterroger

Excellent info here, I am currently doing some research and found exactly what I was looking for.My Blog

July 15, 2015 | Unregistered Commenterkareen walton

to make your work easy vacuum cleaner is really helpful. this will surely save your time and clean everything in short span of time.

September 13, 2015 | Unregistered Commenterneohousecleaning

They do still have the stupid plastic drive gear in. My (white) AirRam sucked up a shoe lace jammed and shed the teeth on that gear. As mine is out of guarantee I took it apart myself and could have replaced it if Gtech supplied the spare but they wouldn't!

If you can't repair it/have it repaired don't buy it - never again.

September 28, 2015 | Unregistered CommenterGarth

Does the upgraded AirRam K9 have an upgraded gear assembly? That is the only reason I wont buy another one. I LOVED it until it stopped spinning, but you cant buy the part from GTech :(

November 29, 2015 | Unregistered CommenterChrissy

Gtech have agreed to replace my AirRam because it actually had a five year extended warranty. So you could try that if you registered your appliance after purchase.

They explained the stripping of the gear should not happen normally as there is a cut out that stops the motor in case of a jam. Sometimes the cut out does not work as in my case.

November 29, 2015 | Unregistered CommenterGarth

Unfortunately I bought a "reconditioned" one from Ebay, and when I dismantled it, after it had died. I found it had some tin foil wrapped around the gear! Enought to last me about 6 months, but too long for me to return it.

Good of Gtech to repace yours.

I have ordered a new K9 direct from Gech, and hoping for the best.
