Yep, I have one. They are really nice. Don't know if I will ever be able to go back to a regular helmet. The 1125R's mirrors are great for seeing your shoulders. The Reevu is comfortable, fairly quiet and not too heavy.
Ordered mine from the UK. (http://rearview-helmets.com/) 250 Euro. Around $335 at current exchange rates. Dollar a bit stronger now than when I bought.
