Got this fin for finswimming practice, this is my first monofin. Overall build quality is very good, it looks very nice. I cracked the blade by hitting it on the pool wall (nothing serious) but I would recommend getting blade protection If you are going to be using it in the pool. I found the foot pockets to be a bit too tight but I have been told that this is very common with monofins and that I will get used it it with some training (only made 2 sessions with it so far).
