Review: An excellent small keyboard with tracker pad. - This has been an invaluable addition to my keyboards. I use it a lot of the time.
Review: love this keyboard - but touchpad buttons are a little too small and fiddly - So close to 5*s but the touchpad buttons are just bit small and fiddley Other than that it's great, I use it daily for work, it's nice and compact which takes a little getting used to but that's the same with any new keyboard. The keys are proper clickey ones with a nice feel. Works on Windows, Ubuntu and Raspberry Pi. I like it so much I bought a second one that my son uses on his Raspberry Pi, he tends to give it quite a lot of abuse dropping it and so on (he's 9) and it's still working fine. Another plus for the Pi is that it only uses one of the 2 USB ports allowing you to use the other for something else (USB drive, Memory Stick, Wifi dongle etc) All in all a great little keyboard.

### ⭐⭐⭐⭐⭐ An excellent small keyboard with tracker pad.
*by C***R on 21 January 2025*

This has been an invaluable addition to my keyboards. I use it a lot of the time.

### ⭐⭐⭐⭐ love this keyboard - but touchpad buttons are a little too small and fiddly
*by E***R on 27 January 2014*

So close to 5*s but the touchpad buttons are just bit small and fiddley Other than that it's great, I use it daily for work, it's nice and compact which takes a little getting used to but that's the same with any new keyboard. The keys are proper clickey ones with a nice feel. Works on Windows, Ubuntu and Raspberry Pi. I like it so much I bought a second one that my son uses on his Raspberry Pi, he tends to give it quite a lot of abuse dropping it and so on (he's 9) and it's still working fine. Another plus for the Pi is that it only uses one of the 2 USB ports allowing you to use the other for something else (USB drive, Memory Stick, Wifi dongle etc) All in all a great little keyboard.

### ⭐⭐⭐⭐⭐ Good quality keyboard with decent keys and some weight to it.
*by B***N on 23 May 2013*

Not the cheapest keyboard, but still fair value at around £23 post free. We've had a couple of them over the years, one several years ago, and it still works like new despite the daily hammering, since it's connected to our TV PC. The keys work well, and the markings are clear and do not wear off in a few months. The touchpad is particularly good and supports multi-finger actions. I'd prefer the touchpad to be on the right, but that's just me! Recommended.
