I'm sorry that I didn't listen to my friend and bought the agv k6. It's incredibly noisy even at 80 kilometers per hour, you can't travel for more than half an hour without earplugs. The top ventilation broke on its own from the first week, resulting in constant air leakage. In the winter, I seal it with tape so that my head doesn't get cold. It looks great, but that's about it. I won't choose this brand again after wasting these 400 euros

In 3 months, the helmet noticeably loosened in terms of fit. After 1.5 years, the visor mechanism became loose (without me ever tampering with it) and the whole visor was creaking. When I removed the cap to tighten the mechanism, the cap broke in my hand as soon as it came off. Something similar happened on the other side, since then the noise was louder because the visor did not secure properly as it should have. The visor broke at the latch after 2.5 years, I should mention the small cracks that appeared around the pinlock on their own. Also, within 2.5 years, the entire mechanism of the top vent broke on its own, it simply disintegrated and the sun visor got stuck. Overall, I was not satisfied, I should also mention that I wore it daily.

The helmet is value for money. Inside the box, it comes with a tinted visor and pinlock. I am slightly bothered by the right ear because I have the intercom, before I put it on, I was fine. After 160 km/h, if you don't have your head straight, you can hear the wind quite a bit from the air vents.

I just bought it and tested it on a 1600-kilometer trip. I didn't find anything negative, so I am completely satisfied

The helmet is really top-notch, especially for the price. As a comparison measure for full-face helmets, I have two Shoei helmets (xr-1000 and xr-1100). It is lighter (a significant difference), has better ventilation, better visibility, and a top-notch sun visor. It also came with a free second tinted visor (which costs 70 euros for Shoei). As for the noise, yes, it makes a noise at 110-130. In the city, not at all. I never had a Shark helmet and I was really impressed.

I have it for 2 years. Despite its positive features, the helmet does not fit at all, resulting in a torturous driving experience

Excellent helmet, sturdy, lightweight, with good sound insulation. The sun visor does an amazing job. The only thing that concerns me is that it hasn't yet taken the shape of my head, resulting in it pressing on me and leaving a mark on my forehead after an hour of riding, but over time it will fit better. It's worth the money.

Positives:
-lightweight helmet (1390gr)
-comfortable fit on the head
-comfortable fit for prescription glasses (feels like you're not wearing a helmet, they go on and off easily)
-impressive sun visor, making riding with the sun a breeze
-externally it may get warm when the sun hits it, but inside you don't feel anything
-very good insulation against the cold, keeping the head warm on cold days
-quick and easy application of the included Pinlock
-from the moment you wear it, you feel safe, something I didn't feel to this extent with my previous helmets

Negatives:
-produces a slight noise at high speeds, but nothing annoying
-maybe the price, but it's somewhat justified due to the carbon it's made of
-the double ring it has, but it's a matter of getting used to it until you learn to do it quickly

Is it worth it?
If your budget allows it and you want to invest in your safety, YES.

Excellent carbon helmet at a very good price. Especially if you wear it and travel, it has such sound insulation that impresses you. Very good quality at a reasonable price.

The helmet fit me perfectly! It feels like I'm not wearing anything at all. Additionally, the carbon fiber weave makes it exceptionally beautiful and lightweight. The only downside might be the wings it has at the back, which are aesthetically pleasing but produce a bit of noise. Overall, though, it is definitely worth its money.
