My order has never arrived

I wrote two emails regarding the missing order without any response. No refund until now

Almost Perfect

The only issue that I have is that the adjustment and inner helmet sometimes rest on my ears. Sometimes I get the perfect adjustment but other times I am adjustments mid ride.

Once the helmet has that "fit" i consider it to be a great helmet.

Catastrophic Service!!

Really bad communication. No answer on my mail to you since weeks

I like this helmet

My biggest issues were self-imposed: I didn't transfer my mirror right away, and I had to start wearing a cap all the time because I'm used to having a visor on the helmet. I absolutely love the light. I'm not worried about it falling out or coming loose. When I put the light in the arm band, it is extremely difficult to remove on purpose. I do not worry about losing it. Ditto the Fireflys. I love how the app syncs the lights and functions as the turn signal switch. So far, I am extremely satisfied with this helmet.
