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%!

The Rii Mini Keyboard vs The Lenovo N5902

In this video I decide which of these two HTPC keyboard remotes I like the best. Purely based on the specs, the Rii Mini should have the advantage because of its bluetooth capabilities, however, as is often the case, it's a little bit more complicated than that.

Great review, I think I laughed more at the comments in that than in any of your other ones!

I still have no need for a miniature bluetooth keyboard but the Rii would win simply as I could wind up the cat something rotten with the laser pointer.

@Voyager. Good point, I didn't factor-in the feline irritation qualities.

Do either of these function at the BIOS screen of a PC, in other words before Windows drivers are loaded?

I have the mini keyboard... it was a perfect thing but it stopped working after few monthes... I don't know why the receptor is not recognized anymore by windows...

i've had the non-trackpad version for a while
same as this -
no trackpad :)

runs samsung galaxy tab just fine
poss. old version of the model you reviewed. worth investigating

I already have a Rii mini Bluetooth (for about a year). And there are a few differentses with yours.
Mine has the model number: RT-MWK02
The Keyboard itself has no rubber but plastic rounded clicking keys (same as the lenovo) and is very smooth to type on.
And the keys are all separated. So i have no movement on the other keys when typing.
(I can send you pictures of mine if you are curious)
Mine also makes better drawing circles.
I'm very happy with it and think its better then the Logitech diNove mini i had for a while

Always like watching your video's.
Bought the #11 after that video and when the battery got screwed i bought the #16 after watching that video.
Great for making video's from my kite's up in the sky.

I just bought the 2.4ghz RF version of the Rii keyboard and so far I haven't seen any of the problems you highlighted on the Bluetooth one.
- the keys don't seem to miss any presses, even from across the room.
- i can draw a decent circle on the touchpad without straight bits.

My research on Amazon pre-purchase made me think that the quality of the Bluetooth connection was much lower than the RF version - I guess you're happy with the Lenovo but if you do another round-up later it might make the comparison slightly fairer?

I have had the Bluetooth Rii for about 9 months now and I agree with your issues with the trackpad. I use it on my HTPC running XBMC so I don't have a lot of use for the trackpad most of the time. I also find that the keys sometimes become unresponsive for a couple of seconds, and occasionally it will input a character multiple times rather than once. I have the version with the plastic keys rather than the rubberised ones and it feels pretty good to type on. At the time the Lenovo Mini was double the price of the Rii so it seemed a better option. If I was purchasing today I'd definitely get the Lenovo.

@Rob Looks like the Bluetooth model is one to avoid then. I really wanted to test a Bluetooth keyboard vs a RF to see what advantages (if any) they had. I've got a house full of mini keyboards now, so won't be testing any more for quite some time.

I found this on ebay:

Some kind of mutated Lenovo.

March 7, 2012 | Unregistered CommenterGideon

Yes - I know. This is a very old test. But thought I'd add something. You mentioned issues connecting across the room to a PC. I've been having problems in general with all sorts of dongles including a bluetooth on a device VERY similar to the Rii - I think it's something to do with generic electrical interference. I stuck the dongles into a USB extension cable And moved the dongle a good 5 feet from the PC. And now no issues even at much greater distances.

With the version of the Rii Mini I have (an rf version) there is an indication on the edges of the trackpad area that points out it can be used for scrolling. It works good enough to scroll pages in a browser.
Works nicely for old school emulation games as well with the dpad and some random buttons on the left being A+B
Sadly my infant chewed up the first one, so I had to get a new one wich sadly lacked the laser pointer, even though the chassis still had the bulge for where the diode would have been placed.
