Started off well, but deteriated after 4 weeks!!
on 13 February 2017
Did originally say "100%", but after 3 or 4 weeks they began to steam up/fog!! And because I chose the darkened glass it's pretty much game over after 100 metres😨😨. I most likely won't use them again as the plan is to swim continuously and stop starting isn't an option.Its a shame really!!
