so far the best goggles I ve owned in 30 years of swimming in pools and surfing ( I use them when surfing as well) -the only downturn : fog up a little as all goggles I ve had
-the best part: they don't leak and provide the best global vision even in ocean swim

and the great design might even keep the sharks away haha

I swim in pool indoor and outdoor and in the ocean either surfing or swimming ...not a drop of water and  positively the most comfortable goggles I ever had ( I swim for 20 years)they  still  get a little foggy in cold ocean water tho

You don`t see as clear and distortion free as other cheaper models. Wouldn`t recommend them for serious swimmers.
