The item is perfect for what I needed it to do. I had to light up some LEDs and didn't want the hassle of buying multiple CR2032 batteries every time they ran out, so this has helped tremendously by having it plugged into a USB cable outlet. Now I can keep them on 24/7 without any issues. Also, The seller had very good communication too and the item arrived on time.

Would definitely recommend buying from them 👍

I just received my keyboard and it is amazing. The key switch pressure is perfect and the size of the keyboard is really really great. I tested it out with all the systems I have around here and it worked perfectly out of the box.

My full sized spare keyboard is now put away. This is just a bit bigger than a business card and keeping it on the spares shelf is great.

A few details about why I purchased it:

1) I work with a lot of virtual machines at my desk and sometimes need to work with additional desktop systems and micro form factor computers like Intel NUCs. Normal sized keyboards cannot be stored cleanly and take up too much space and most of the wireless off the shelf keyboards are NOT proper thumb oriented typing keyboards. The wireless keyboards are WAY WAY too large and using them tires out your hand because the key pressure is always far too high.

I thought this might be a great keyboard to use as a spare when doing installs, quick system configs and testing. I just recieved it, tested it out for about 15 minutes and it has already replaced my spare keyboard.

2) I have been looking for good examples of thumb keyboards as I have wanted to learn enough electronics to build a blackberry sized keyboard with my own layout. This is an AMAZING thumb keyboard. I am going to try and use it to see if I can get my thumb typing proficiency up to the levels I was on Blackberries.

What the creator this device managed to do, in my opinion, is make the keyboard the perfect size. It is just small enough to be perfect for thumb typing, the feel of the switches is excellent AND having the top pcb act as a cover PERFECTLY makes this thumb keyboard feel like a usable and quality product.

3) Lastly, if you look at the Bobricious line of keyboards and computers, they all have a quality design and finish to them. There is something very odd about his design aesthetic. He didn't just make a thumb keyboard to be purely functional, he spent time making it beautiful. First, he put a top pcb on the device and used the correct size switches with a nice feel that won't tire out your fingers. Then he select a unique black and gold type of layout, which is very nice. Then, on top of that, he added artistic touches like the Bobricious logo in a cursive font, the spock live long and prosper hand symbol (awesome, love the Trek reference) and just overal really lovely use of fonts, layout and led status lights.

I love works of art and I really think the designer brings something extra to even something as relatively simple as a usb thumb keyboard.

4) I may have to buy a second one and add it to my kit. On site visits sometimes mean I need to shuffle hardware and having a thumb keyboard for one off quick config / setups might be useful.

Anyway, just logged back in to share my experience of this product. If you are looking for a thumb keyboard with really good switch feel that wont tire out your fingers, you might consider looking into getting one.

Excellent quality, truly a unique product. I plugged this into a number of different computers and it is truly plug and play.

Board is very nice but docs with circuit python are not easy to find. I am a newbie with python. I am working on Bobricius ideas who writes programs with arduino ide rather than python.
I hope to reach the goal to create a Lora transceiver with circuit python. I will keep you informed soon.

Great little keyboard - easy plug and play - looks like it will last a long time - sturdy construction. Would have preferred the USB out to come out from the side - but just a personal thing - at a pinch I could move it, but I won't. Currently using it with 5" touch-screen UMPC - Higole F1 - just not usually enough room on the screen for on-screen keyboard to be effective - this fills the gap in tech perfectly. Thanks Bobricus well done.
A final point - I wear glasses and the symbols embossed on the keyboard face are understandably tiny - really tiny - I struggled to work out what was what at first - but once you know it's not too hard.... it's clear as it can be given the space available - but for those with less than perfect eyesight you need to bear this in mind.
