Speedo always perfect

I chose my glasses because I wanted the speedometer knowing the brand for a long time, and I also was looking for a pair of goggles and which do not form a mist in each length.
Ever since I received them, I swim on average an hour a day, and are completely sealed and without steam.
to resolve this is very easy, even for a child! there is a set point on the side on which supported and it's already done, I'm very happy with my purchase, and I recommend it.
excellent value for money, fast sending and free of charge.
