The spray works better than anything else I've tried so far (including Arena spray). I have it now. Two months use, for 2-4 workouts / week with between 2000-4000 m, on a AquaSphere Vista The view is the beginning of training perfectly clear in the course of training (from 200m) it fogged then always something, but if you can with your fingers from time to time nachwischt, or come in the water, everything is very clear. Other solutions had to 25m mostly conclusion because the fog was again so strong that you could see rather vaguely floats on other tracks. My glasses are about 5 years old and in need of a good cleaning solution pretty good eingedreckt (until recently holding), so I'm very satisfied with the extent of the cleaning performance; I would probably have his glasses once properly basic cleaned to obtain an optimum effect, but as it is, it is already usable. Two small downer are the high price (other drops cost about half) and that it takes a relatively large amount of them, as the liquid is quite viscous, and it accordingly requires a larger amount (I would sometimes appreciate about 2-4 times as much as in the arena) to wet the entire surface. With the recent restriction but I can in any case say that it is the best solution as far as functional, I've tried. We'll see if you can get a family package for a better price ...
