Corrective Lenses For Scuba or Dive Masks (Mask Not Incl.)

I bought these lenses to be installed in a ScubaPro mask that I purchased separately from another online retailer in anticipation for a dive trip that I just came back from in the Caribbean. I had the dive shop at my dive destination install the lenses and it worked out great! On my last 8 dives I have been using these lenses with my new mask and I am now able to see things underwater with MUCH more clarity. That said, altogether my mask + these new lenses came out to just about $300 (before shipping costs) - which, IMO, is pretty expensive - hence not 5/5 stars. (It looked like to me that there were other companies that sell dive masks selling similar products for about half the price.) One thing I want to do is make a shout out to the OnlineScuba.com customer support staff members Layna and Sierra as they were absolutely INSTRUMENTAL in getting this order shipped to me in time for my trip. The customer service on their part was a 10/10! Thank you both SO much!!! Instructor Bill: Thanks for your review. As for half the price would want to make sure we are comparing apples to apples.
