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?

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.

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

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.

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.

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.
