Again, I send anticipate again that I always valued according to price / Nutz / performance ratio. So even with a swimming goggles that costs less than ten euros and me as an opportunity swimmers (2 times a week / 40 minutes) saves red eyes from chlorine.
The glasses are not professional equipment, but all in all absolutely capable. Does not fog up minimally, can be good set and fix. The fogging is but normal people that are cheapest plastic lenses that are produced in the Far East in mass. What do you expect here? Again and again, think about it, that the glasses UNDER costs ten euros.
And when things steam up a bit, then take the glasses off briefly, dipped it in water and put them on again! Lasts exactly 11 seconds, and it can go on. The 11 seconds is yes on each.
Therefore here again in my view 5 star, fits all served their purpose, costs little, comes with goggle pocket !!! and everything in butter.
