Interesting ploy -- throwing in a last minute perk to try to make their funding goal. First time I've seen that. They do look close enough to hit it (maybe even without this).
We have a blue line innovations reader, and found it pretty helpful. Their software is atrocious, though, and the reader stopped working after 6 months. WattVision a far superior UI and has always looked interesting to me, but I'm not sure I want to spend $200 on it.
Too bad wattvision doesn't make anything that can read my meter :(
