Bought it for 16€ due to good reviews.
Pros: 1) Provides good protection from cold temperatures, around 10 degrees.
2) The mask allows for good breathing.
3) It seems quite high-quality.
Cons: When wearing it with my HJC i70 helmet, the plastic mask gets stuck and needs to be pressed down with the hand to lower the helmet, then pressed up to get it in the right position. I believe this problem may occur with other helmets as well.
Conclusion: It is of good quality but not practical at all, and I wouldn't buy it again, especially for its price.
Update 17/12/2023: Now that the cold weather has arrived, due to the plastic in front of the mask, the visor of the helmet gets foggy to the point where you can't see anything. It's not worth a single euro. I had to cut the plastic mask with scissors, and now I can somehow use it until I get a new one.
