Better than similar ones from Arena, both in terms of the strap and the rubber around the mask. Used in open water. Yes, they will fog over time but less comparatively.

no leaks, very good seal. one unfortunate thing for me is that they leave a mark on the face - probably exactly because of the good seal.

Water doesn't get in and it adequately protects from the sun's rays, resulting in my eyes not burning after thirty or forty minutes of swimming in the sea.

Comfortable for use both in the pool and in the sea, but it started to fog up from the first month of use...

Very good application on the head, the eyes do not hurt like with regular glasses. Easy to adjust them. I give 3 stars because from the second use they fogged up quite a bit, resulting in the need for the usual tricks for anti-fogging. If they didn't fog up so much, I would give 7 stars, not 5!

When they say wide angle, they mean it. That is, there is a "distortion" in the field of view from their "lens" / glass, so it gives the feeling that you are seeing the image from a go-pro (fish eye lens effect). It has its charm, but it can also be dizzying - it definitely gives a cinematic feel to exploring the depths.

The silicone fits perfectly, but it's just silicone, so at some point the suction cup will start to bother you. For a swimming pool, I would recommend something with a sponge/foam material in contact.

In some fantastic way, it always had water inside, but without me realizing where it was coming from, or if there was a moment when it reached my eyes. It is possible that their geometry/shape stores a little water during the first dive, no matter how much you shake them, and it simply accumulates at the bottom of the lenses. It doesn't blind you, and it doesn't reach your eyes, but it's there and you can see it, so it's not suitable for perfectionists.
