We got ourselves the goggles on the advice of the sports teacher of our son, because his Schwimmabzeichen far fail in large part because he stubbornly refuses diving eyes open under water (it would then burn), but this makes sense when bringing up objects is. We chose the Ispeed Schwimmbrille decided in stylish black, because it is multiple adjustable and can therefore be used by other family members. The spectacle is held securely in a sturdy plastic storage box (no bag!). The glasses can be resized sideways on an elastic band, as well as in different sizes are three nose pads to exchange. Unfortunately, so far lacks the operating instructions. Sure, for the spectacle this is not really necessary, but the nose bridge replacement is not so easy and with brute force will not be the spectacle indeed treated equally and possibly damage. Otherwise, the swimming goggles have the typical silicone rings around the eyes. The glasses sitting well, first bothered me in the dry the tight fit, in the water but he was hardly felt. Underwater spectacles was absolutely tight and after surfacing as I wear glasses could not determine the commonly occurring otherwise tarnishing of lenses. Even my son now ventured with the glasses with his eyes open under water. As such, we are satisfied with the glasses, remains to be seen what the sports teacher says
