Caution......pool products and customer service. 3 sets of glasses order over the last year and all have defects. Frames on first set were too large, but we weren't told that we should have ordered smaller ones from them until almost a year later. 2 other sets of lenses ordered and 3 of the lenses are not to prescription. One was so bad that I had the old lens put back in to read street signs. After sending documentation, business sent checks refunding costs, but then put stop payments on the checks. So in addition to having bad glasses, we're also out $30 in bank fees.
