Review on Frameless Scuba Diving And Snorkeling Mask: Tilos Excel For Free Diving by Johnny Burns

I have no clue what the person who rated 4 star is talking about. There are no pins in my mask. The strap is clipped in using a clip. It clicks in place, and stays in place. It is very easy to remove.The view though is spectacular and I couldnt recommend it more. The low dip in the mask provided me more view to the bottom of the sea while diving. It is so comfortable and so light weight.Fog is also not an issue if you just do a rinse with baby shampoo.This is the best mask I have ever used. The view is uninterrupted! 5 stars all the way.
