For their price, they are good.
An entire summer in the sea and the anti-fog coating remains.
I can wear them for half an hour and they don't get foggy at all.

On the downside, the sides do not have a proper fastening to stay at the length I adjust them, like other goggles do. Every time I wear them, I have to readjust them.

Also, the application of the suction cups on the eyes is not the best, at least for my face.
If I wear them quickly, either they will press my eyes excessively or they will leak water.
They require a lot of attention to apply correctly.

I bought 2 pairs for the kids, unacceptable, the connections broke in 3 days.
User ARENA for 20 years, such a terrible product for the first time.

Very high-quality glass, seals on the face and you see very clearly. I just hope that at some point completely anti-fog glasses will come out and we won't have to deal with this at all.

Very lightweight. I wore them for 45 minutes and no water got in at all. Without creating a strong suction and bothering the eye, they have a very good fit. I admit I didn't expect them to be so good!
