Helm

The only words I have are "Excelent" Wow what a helmet, I am very happy to have this helmet, it is very confortable, it adapts to my head perfectly, it is cushioned very well and the helmet visor is just excelent no bugs in my face, totaly transparent and you can use sunglases, no problems with polarized sun glases and I can see my Engine pro display with no problems!!! I suggest that everybody should buy the Engwe Smart Helmet for these reasons and because you can also answer phone calls and listen to music !!!

j'aime la visière qui descend très bas et son look, un peu chaud pour l'été car il y a une doublure complète et pas d'aération.

I've never had a helmet before. But I like that this helmet can be adjusted to one's head size dynamically (which probably all helmets can). The Bluetooth system is easy to handle, but since there is no coverage of the ears (hence only 4 stars), this soon becomes obsolete, since the wind while driving makes phone calls hard to understand. (And listening to music is also quite impossible for that matter.)
The fact that ears are not covered might be good for staying alert towards surrounding noise (which I like!), but on cold days this certainly will cause cold ears.
