I bought the above mask last summer. I believe it is amazing in terms of quality and fit. It definitely worth the price difference compared to the simple masks that cost 10 euros. Since I have only used it for one summer, I cannot tell you if it will last for years with proper maintenance. I used it for dives up to 7 meters. One thing bothered me though. Compared to some other masks in its category, the gopro camera screws onto the mask with an allen screw. It is somewhat tiring either if you use your camera somewhere else or if you simply want to make an adjustment while you are in the water without having the characteristic gopro screw and needing to take off the mask and use an allen wrench.
