I used it a lot, from June to September, at least 5 times a week. The first month I was very satisfied with how it blurred, but then it started to bother relatively quickly and from a month and a half onwards it became tiring, needing cleaning every 2-3 minutes. The respirator is very good, I have no complaints. In short, if someone wants it for occasional use, it is pleasant... If someone wants it for frequent use, then they should look for something more high-quality.

Fantastic mask, no water enters and it doesn't fog up at all. I have used it 3 times for 2 hours each time.

It fogs up incredibly, and I even tried a liquid anti-fog solution, it also leaks water in the nose. I really regret spending my money on it....

I didn't use it for many hours, but it doesn't fog easily.
4 stars because the snorkel that comes with the mask is too small.

Both the mask and the respirator are of excellent quality.

Overall, I am satisfied with the seal, it depends on how I wear it, sometimes it may require small adjustments to be completely airtight. Even when there is an issue, we are talking about a slow influx of droplets.

For me, it becomes foggy but it does so slowly and gradually, so for me and the use I give it, it is not something tragic.

The mask is lightweight and compact, it has excellent silicone, very good lenses and it really doesn't fog up. The +++ is also the very good breathing tube that comes with the set.
HOWEVER, personally I had an issue with the frame that digs above the nose and bothers me. (it has nothing to do with excessive tightening). I gave the mask to a friend of the group and he had a similar issue.
Despite several tests and adjustments, the problem was not fixed.
It's a shame because even though I am a longtime fan of Cressi, this particular purchase did not justify me.

Perhaps the best mask I have worn in the last 3 years. I am not a professional, I just enjoy it very much.

I won't bore you, I'll just say a few things.
It doesn't take in water, it doesn't fog up because it has a special filter on the nose, it has very good materials, and it has a very good breathing valve!

The mask indeed does not fog easily, it has a pleasant fit on the face that doesn't pressurize you. It doesn't let water in easily, although this also depends on other factors such as whether you have applied sunscreen, face shape, etc. Overall, it is a good mask, lightweight and soft. However, because the lenses are closer to the eyes, depending on the angle you look from, you may have the sensation that objects underwater are closer. For example, you may think that the rocks are closer to you. It is a matter of habit and adjusting to the way we look underwater.

Maybe the best mask I have worn in the last 5 years. I am not a professional, I just do it as a hobby and use it for spearfishing. Its small volume and great visibility make it stand out and comfortably compare to masks from the market that are much more expensive. If it ever breaks, I will buy the same one again. If you clean it properly after each use and take care of it, it will last you many years.
