U.S. Divers Avalon Mask

I swim every day in a pool. Because of health problems, I wear a diving mask to keep pool water out of my sinuses and eyes. I bought this mask because of the purge valve and the price. It is a nice, heavy mask, but I discovered quickly that it wasn't the best option for me. Unfortunately, the purge valve is in the wrong place and does not allow the mask to drain completely, plus it really pressed on my cheek causing discomfort while I was wearing the mask. The fourth time I used the mask the plastic pin that holds the strap on snapped in half. I contacted Swim Outlet via their live chat and their EXCELLENT customer service department gave me a full refund and I purchased a different mask.
