Tiny, functional, interesting! I Love her, but she wont charge 🫠
✨️UPDATE: Got the replacement, and she works like a charm! 🎮❤️ +2 stars! (Original review Below) 1. Size: let's be honest. If you're buying this product, chances are it's because you want something miniature, novel, and functional. The thumby does exactly that....and very well! 2. Appeal: personally i am a huge fan of miniature things, and tech. The inner nerd went crazy when Thumby introduced a miniature piece of tech.... and you can program your own games and imagery, also?! Love that. 3. Quality: the little device may be a challenge to control and use due to its size, but there is no lack of quality in the feeling or function. The keys are satisfyingly clicky, the material feels nice, the special black-grey display adds a subtle hint of depth to the retro games, and the tiny sound feedback that it produces gives you just enough to emulate a nice, retro, portable game console. 4. Downsides: first and foremost the packaging is cute and minimal, much like you would find on any novelty item. There is basic information such as what games come pre-loaded on the device and where you can go to download more games or program your thumby. The biggest miss here is that there are no instructions or user manual. I had to google the information for charging the device, and read through the website's FAQ section. (Maybe include a QR code or link to an online user manual?) Another problem, which hopefully is just device specific; mine wont charge... whatsoever. Only way I can use it is if it's plugged in to a power source. Started an exchange for mine, lets see how the replacement does! (-2 stars for this alone) Overall: i absolutely love the concept of this little device, its so small it takes up less space than a flash drive, and i loooove that you can program your own functions or even select from other pre-made games and functions that other users have created.

Fun lil doo-dad
This thing is too cool, very fun keychain candy, works great and the battery has lasted quite a while without charging.

Absurdly small, a lot of fun
It is the size of a small flash drive and be ause of that the D-pad can be a bit challenging to use, you have to develop a technique. And there is a quite a few games for it, the best ones I have found so far are Guiguitte (tribute), OutThumb and Gravity Challenge. There's also sudoku,but too small to see. You can of course write your own, if you are so inclined, there's a whole browser based SDK for it. And it does have sound output, just pretty quiet. But hey, think how cool you'd have been as a kid in the 90s if you brought something like that to school. You need to install "battery" to be able to check the battery state, as the default UI doesn't have a way to check it. Also it literally has a smaller screen than my flashlight.

Good product and great customer service!
I've had two Thumby's for a little over a year now. One of them I keep on my keychain and the other in my desk at work. The screen for the one on my keychain recently stopped working. Possibly due to it being jostled around or getting wet while attached. I reached out to their customer support to see if there was a warranty or a way to fix it and within minutes they emailed me back saying they would send a replacement; no questions asked! If that's not great customer service, I don't know what is. It only made me want to buy more! Overall, this little thing is extremely well made and, for the most part, can hold up on a keychain, assuming you're not getting it wet. I love the fact that you can download other games to it through their website, and their discord has an active community if you were interested in making your own games for it and needed some help. They have a Thumby Color launching on Kickstarter soon as well, so I highly recommend checking it out if you want a little more "umph!" with your Thumby.

It's so small!
I love this thing for a lot of reasons: - Very sharp screen contrast - Super customizable - Awesome web-based IDE for coding on the go - Sooo small and cute However, the size of the buttons and screen is definitely a problem. Fatigue comes up quick with this one. Also, for the price it would have been wonderful to have included a Bluetooth module - but at the same time you really can't argue with the excellent battery life. Just hope that you have a USB A-to-micro data cable handy whenever you want to code on the run. I also haven't been able to get the IDE to recognize the Thumby through an Android device.

The rope it comes with went loose a few days after buying it and I lost it, terrible that they'd ship it out with that loose of a knot with that weak of a condition
