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%!

Two new videos, A Crystal Watch and an OBD-II Display

Here are two new videos. 

First up, the Phosphor Appear Swarovski Crystal Watch. Not the typical type of thing that I make a video about, as it doesn't have a lot of functions. It can either tell the time or not tell the time and that's it. What it does have though, is an interesting time-telling mechanism.

It can be purchased from here 

(although wait until 1st November for the price to drop by 20%)

Secondly we have something that's a bit more into my usual territory, and that is technology for technology's sake. This OBD-II LCD Display is the kind of thing that no one really needs to own, but it's pretty cool nonetheless. I know that people really like adding gadgets to their cars and this is one of the more potentially useful ones. It may even pay for itself eventualy, if it makes me drive more economically. I made a really annoying mistake whilst doing the voice over because my brain insisted on saying ODB instead of OBD (I must have dead-rapper-itis). I didn't feel in the mood to re-record the whole thing, so please transpose those two letters for me when you hear them. I've sacked the quality control team.

Again this came from Chinavasion here 

Chinavasion have been selling this since last year - but today it has also appeared on Dealextreme under the name V-Checker A301. Mine doesn't boot with a V-Checker splash screen - but it appears to be the same device. Here's the manual (for what it's worth).

Hi there. I was just wondering how precise the watch is. A friend of mine went to Shanghai and he brought me back a "Rolex". It looked pretty nice but the time was off about 17 minutes a day :)

Interestingly, there *is* an update file (v 3.40) available on the site, but there's no information on exactly how to update the thing. I hope the manufacturer can be convinced to include the option to switch to Imperial measurements...

@Willydilly - It's holding time fine - Phosphor watches are a reputable company that have been making e-ink watches for a few years now.

@Glen Richards Thanks for the info. I'm pretty sure that it's going to stay metric only, I'd imagine imperial support would be a non-trivial update.

Is the speed displayed adjustable to show true speed, not what the car says its doing, which can be 10% out?

Thanks for the video with the OBD display. Perfect! I bought it yesterday!
Can you give me a tip on how you installed it in your Smart?

Thank You

Hi there have been searching for some OBD devices and stumbled upon your old post. Just wondering how does it hold up over time? Is it durable?
