Resurrecting this thread as there are a few reviews out now.
MTBR really liked it and the only downside they saw was the price along with proprietary bottles.
A womens biking blog Liked the bottle and design but after knocking it out with her knee she no longer considered them useful.
I have some money sitting in my paypal account and prices are as low as $36 at treefort plus shipping.
If I get three posts that want me to buy I will so an unofficial indepth BF review.

It is destined to go the same way as the velcro mount for water bottles a couple decades ago . . .
Simple, clean, light. If it works, I like it. Cages suck. They muck up your bottles and don't always hold them so great either.
If I could figure out how to buy it I might do so. The guy's website doesn't work.
