iPhone 6 Diving Case, iPhone 6S Diving Case, Senrn Professional [40m/130ft] Dive Swimming Underwater Photo Video Camera Waterproof Case Cover for Apple iPhone 6/6S 4.7 inch + Lanyard - Black

Works great. I got my Open Water certification and used it on my final dive when I went as low as 22m; as well as snorkeled with whale sharks and it worked as described.One thing to watch out for, after I swam with whale sharks in the morning, the next part of my trip took me to a waterfall swimming area which I also made use of the case. I saw after I was finished swimming that the case had fogged up on the inside and the pictures came out really bad. Not the fault of the case. Just really make sure to put in a completely dry phone as any moisture will fog it up since the phone being on max brightness and always on will make it warm and cause the case to fog up on the inside.One other thing I just thought of is that the strap it comes with doesn't seem to be very heavy duty; before its next excursion I will be looking into finding a better strap to work with it. You definitely do need a strap though, with my iPhone 7S in it, it doesn't float.As far as shipping, I think everyone's mileage may vary. Mine took exactly 20 days. The seller shipped it out fast; it just took a long time through customs since it's coming in from overseas.
