My first pair lasted about a year then started to leak a little. The basic pair aren’t mirrored which can be a bit uncomfortable if you’re outdoors in strong sunlight, but on the other hand really good if you are in a dark pool or outdoors on a dull day. Now ten months into my second pair (mirrored, this time). Shame they don’t have the little mesh bag any more, I eventually lost it. 

good seal, nog mist when wearing for wuite some time.

Strong goggles that don’t leak or mist too badly

Comfortable goggles, that I find great as training goggles as well as for racing.It's a shame that these no longer come with a net bag to store these in.
