            Beating the winter weather

            Bought this to use with our cold midwest winters. Used outside this past week with 8 degree temps and phone continued to work just fine.

            Works out

            After modifying it it fits in my purse, protects my iPhone, and makes it easy to grab. I had to shorten it to fit my iPhone Mini by hand stitching it across the bottom but did not cut the bottom off below the stitching which gave it some needed height & stability.

            Very very snug

            Honestly I haven’t used it as much as I wanted because it is such a tight fit to the phone I can’t get it in our out without major effort. I had iPhone 11 when I got it. It’s a bummer.

            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.
