Good quality construction inside and out, easy closure and use of the visor, easy removal of the visor. Installed intercom that works very well.
It has 2 negatives: when the visor is closed, it presses more on the cheeks. It is very annoying and needs to be slightly open.
The medium size is exactly right for me, wearing a small Arai (54-55).
It is also quite heavy - but probably at this price, everything is like that.

Negatives:

1. For some reason, the air passes strongly into the eyes, causing pain (I'm talking about cold air). I have never experienced this issue with any other jet helmet, even cheaper ones.

2. With the air vent closed, you feel cold on the top of your head. This has never happened to me before.

3. It doesn't fit in the seat. This is also the first time this has happened to me because my scooter has a large space in depth/height. Maybe I should have studied the dimensions in the specifications before buying it. I didn't even consider that I would have such an issue.

Positives:

1. The construction quality of both the helmet and the visor seems good.

2. It takes pinlock, which I have installed and it works perfectly.

Conclusion:

> Don't buy it for winter use and don't buy it if you don't have a top case.

> Buy it if you want to wear it in all seasons except winter, if you specifically want a jet helmet with pinlock compatibility (of course, what's the point of pinlock if you can't wear the helmet in winter), and if you don't mind placing it in your top case.

P.S: As for the size, it fit well in the size I always wear (large), although it was a bit tight on the chin (it will loosen over time). I didn't mention the "noise" issue at all because we're talking about a jet helmet, so you can't avoid it.
