The helmet was pressing my head until it opened, resulting in a headache.... after a year of use, the visor closes on its own and the helmet is supposed to be open, but it only closes with the first shake.. useless!!!!

Given that it is a product from the lower shelf (economical) and with standard safety certifications, it is logical for it to suffer in comparison to similarly priced products in other characteristics. I use it within the city and for short distances outside. Also, my driving is not fast, so I do not have an opinion on aerodynamic behavior and noise after 100 km.

Its weight is a positive aspect.
Its negative aspect is that it has a slightly tight fit, so it is good to try it before purchasing.

I am fully satisfied with this specific product and its use, and I highly recommend it.

I have had this helmet for about a week now and it puts a lot of pressure on the cheeks near the chin, and if you wear it for a long time, it hurts. This may be due to the fact that the materials are new. The second problem is that in the front, when you wear it, the flexible plastic for the nose appears to be crooked. Other than that, it's okay for its price. Here I uploaded a video for you to see what I'm referring to: https://youtube.com/shorts/FUt0ROM2wVk?feature=share

I have saved my head, and not just once, but twice so far. Once with a scooter and once with a bicycle. And in both cases, I didn't pay a kidney for the helmet, normal things. So. When 35 years after the last ride, I decided that I had to hit the road, first and foremost I bought a helmet. This one here. The scooter came next (BmwF 650 CS Scarven.) With the helmet, little things bothered me. For example, a screw that holds the visor, it got loose and rattled. I tightened it - problem solved. After 60 km, you hear the wind whistling a lot! After 100, Panic!!! I consider it normal. On a long trip, I will wear earplugs. That's it! I like it and it covers me perfectly! Thank you!

I bought two helmets, one in white and one in black.
Quality materials compared to its price.
It fits well. Quiet up to 80-90 km/h, then it has a slight noise up to 120-130 km/h that I have tested.
The visor doesn't bother you in any angle of view, but it can fog relatively easily.
The sun visor is excellent. The sun doesn't affect you at all.
I think it's one of the best at this price

The internal tinted visor is of very poor quality, to the extent that it creates idols and makes you dizzy. Its aerodynamics produces a lot of noise.

Obviously, it is a cheap helmet from which one does not expect much, but well-known companies should either not produce cheap products or, if they do, not tarnish their name with them.

The comparison is always made with helmets of the same cost that I have tried, and even from companies that are not as well-known as Acerbis.

It would be value for money if it cost 40 euros.
