As a helmet, it looks nice but the construction quality is very low. The visor came off while I was on the road, I fixed it on the spot with a multitool, and the second time it happened again but I lost the entire cap on the road, and now I am without a visor

It's worth its money up to a dime. Offer for 69€!
Tight at first, maybe a little too much, but it quickly broke in and fits perfectly. It gives you a sense of security and quality. With the visor down, no air passes through at all, ideal for winter.

At a price of 100€, it is "fair". The quality of its parts is comparable to NOLAN (as far as you can tell by touch and sight), while the support of the spine is very good and I haven't seen any other helmet in this price range with something similar. The truth is that it fits better on the head when the visor is closed and you feel it more as a part of your head. Relatively lightweight (weighing 1.28kg) but at speeds of 100-140, it starts to feel lighter. There must be something with its aerodynamics. It has more noise from the air and slightly more fogging compared to a Nolan, but the difference is not proportional to the price difference. I use it daily on a maxi-scooter (maximum 160km/h) for 3 weeks now. I will update later regarding durability issues.
