    Christmas present

    Looks great, good quality. Most important, my wife likes it and can’t wait to test it at the beach!

    a tale of 2 sizes

    I bought two Apollo II + antimicrobial cases. One ( seafoam green) fit our phones perfectly, the other (silver) didn't. It is a tight fit to get the phone in and out of the silver case. Phoozy offered to rectify this problem but we were heading out of the county for an extended stay and did not have enough time for a switch. I appreciate the company's efforts to correct this problem.


    A must have item!

    I live in Myrtle Beach, SC. It gets hot! I bought a large. My iPhone 11 and my husbands se6 both fit in it together. This was great at the beach, pool, and golf coarse. When everyone else’s phone was overheating, mine was great and still playing music. My phone didn’t overheat once this summer! A must have if you like to spend time outdoors!

    My 7th PHOOZY Purchase!

    I live on a lake and do a lot of kayaking and boating. In addition to buying two for myself (first one wore out!), I have gifted PHOOZYs to five people and we all ❤️ them.

    I love the fact that my phone is protected and I don’t have to worry about it. I like that it has a ring to put on purse or jeans.
