This helmet keeps all its promises, I use it now for almost a month over three hours a day on my bike to commute. It is very resistant to rain, even abundance (along tempered by a big storm no PB). The microphones are not miracle with the relative wind though. You have to stop or roll slowly. I hesitated for this type of helmet because of my glasses, but I have no problems of irritation or pain despite continuous wear which can sometimes exceed three hours straight The maintenance is firm and allows jogging without problems. It fits very well as a bicycle helmet. Question BlueTooth, all goes well, I use it with a Blackberry, but against it does not support the management of two sources simultaneously (eg PC + phone) is either one or the other) Question sound, the bass is the best quality I could get compared to all-ear headphones I've used. The controls are well thought out and accessible, it must be a little time to adapt but the buttons are prominent enough to quickly adjust the position of his finger.
2011-12-21 Edit: I withdraw my 5 *, there is a week I dropped my helmet on a tiled floor and a branch broke. Obviously the plastic does not withstand such shocks is not so extraordinary, it can happen to everyone dropping his helmet. In addition, Motorola's support has informed me that it was impossible to repair that, no spares.
