Review: It actually works! So cool. - This is such a cool little game keychain! It actually works and has fun games on it. The controls are slightly difficult to navigate because they are so small, but it's worth it. When I get bored, I get my keys out and play it. I let my niece play with it when visiting and she wanted to keep it. Coolest keychain I've owned in a while. It does have little sounds but they aren't super loud and I don't think the sound can be controlled. Still, I love it!
Review: 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.
