To be honest, the wood feels plasticky and the knob feels unfinished. There's also a significant gap between the wood and the bezel. The screen is too small, and battery life is poor. It looks like a premium product, but it doesn't feel like one. I have one, and if it broke I wouldn't pay more than $20 for a replacement.
That's sad. I haven't seen on in real life, just the pics on their website (although I did find out yesterday a friend bought one in their original kickstarter, so I'll be able to hold one soon.)
I do have a bid in on a spare Kindle and plan to make my own though. I really like the _idea_ of it.
