The inexpensive price of this mini keyboard places it in the “not really sure about it, but give it a go anyway.” category.I purchased it primarily for my nVidia Shield tablet on which I have to rely on the onscreen keyboard. Whilst this has large keys and is easy to use, the fact that it hides a lot of the screen at the same time I’ve always felt a disadvantage in use. This is particularly so when radio buttons need to be pressed and which can’t be seen without scrolling the upper, visible, part of the screen.As supplied, it isn’t possible to use it with the Shield immediately as this has a micro USB port and the necessary OTG cable was not included and which is necessary to connect the little wireless receiver. An OTG cable for mini-USB is supplied with the unit, and for charging. Having charged the keyboard I connected the wireless receiver via my OTG cable (female USB to micro USB) and plugged it into the shield whilst it was switched on. Then when I switched on the keyboard it was paired automatically (no delving into settings) and in use there was no discernible delay from pressing a key to the character appearing on screen. The tactile feedback of the little keys is good. I’ve never been much of a fan of track pads on my laptops, so whilst this one works, it isn’t, and I wasn’t expecting it to be, on a par with those. Used with the Shield it is a bit slow and awkward.So it has satisfied my primary reason to buy it – use with my nVidia Shield tablet. Out of curiosity, I tried it with my W7 Professional laptop with which I already use a wireless mouse. After the little Windows prompt following insertion of the wireless receiver, it worked as expected and connected automatically, although the cursor speed using the touch pad is too fast to be accurate when pinpointing on screen. The best news with this set up is that it does not interfere with my wireless mouse and I can now position my 17.3″ laptop a little further away to view DVD/Blu-ray movies, as it no longer needs to be within arms’ reach to use its inbuilt keyboard. This is an advantage that didn’t inform my buying decision, but has simply enhanced it. I found it also automatically paired with my HTC One M8 although nothing on the screen indicated it had. However, I can’t really see myself carrying this with the M8, so whilst yes, one could, I won’t.I hesitated about a 4 or 5 Star rating, and had it been just for use with the Shield, I would have awarded it 4 Stars due to the slight problems using the mouse pad. However, used with my laptop it has opened up fresh opportunities, so for me, the mini keyboard is a 5 Star product.PS. As Think Assemble has a habit of sometimes posting reviews of near-identical products together, I’d just like to reaffirm that this review is for the Rii brand. There are similar units with identical case work but with the secondary key function layouts being different.

This is a very compact almost-qwerty (the keys are in a rectilinear grid rather than staggered) keyboard with onboard storage for its 2.4GHz radio USB dongle and USB-C port for charging. It came with a rather odd USB-A male-female cable that breaks out the VBUS power to a third USB-C plug which means for example you can charge it from your PC while still using the USB port for something else. Cute really.Keyboard action is quite nice – more positive than the usual TV remote buttons you get for example. Radio range is ample for most people’s lounges and because it’s USB-based, the keyboard works for BIOS settings and other non-GUI-OS work which saves having to crouch in front of the TV with a wired keyboard when configuring or installing a new OS.Doesn’t look out of place on the coffee table with the other remote controls.

It really is small, you can fit it in one hand with room for the thumb & little finger to stick out, the mouse is a bit sensitive but with practice you’ll get the do’s & don’ts for a smooth use, so phone size but not as well engineered.

So I have my Galaxy S25 Ultra mounted overhead for filming crafts and with screen out of my reach, this little keyboard allows me to control the camera zoom and other functions from a distance just like you could do with a regular mouse but in a pocket format which is great as I do not want to keep a full sized mouse with pad in my workshop. The wireless dongle is just plug n play, I plug it into mu usb hub connected to phone and voilà I have full trackpad remote control of my phone! Recommended.
