Great product with lots of potential, but...
For Mixtile GENA
*Update: Since writing my initial review the Mixtile folks have stepped-up their support game and have produced at least some documentation as well. Still awaiting the developer documentation but once it's released I expect to be doing a lot of hacking on this device :)*
This is a very impressive bit of hardware for the money, it's well-made and I'm super-excited to start hacking on it.
Unfortunately, there's little documentation so far, however the Mixtile staff have been very helpful and have said the documentation is coming soon.
If documentation becomes available, and if the development tools are usable, this will be an amazing device (and I'll update my review accordingly). In the meantime, if you have an iOS device the built-in firmware works well and has a lot of the more useful features of a Pebble watch.
If I'm able to find out more I'll share here for potential customers, in the meantime here's a more detailed summary of my first impressions: http://jjg.preposter.us/mixtile-gena-first-impression.html

Dear Jason,
Thank you so much for your support and suggestions. We will upload a vedio of quick start for GENA soon. It will have a brief introduction about how to pair GENA with iOS device. More documentation will keep updated.
