They have made some refinements and improvements. I bought one a couple weeks ago and have used it once. I like it so far. I like that I can check what's going on with my beer from anywhere. I ramped up my ferm temp at the end of fermentation and I was able to check from work how long it took to go from 65*-70*. I thought that was pretty cool. I'm going to do a more extensive review on it once I've used it in a few beers.
It would be sweet if you could control the fridge temp online, too.
