            I’m a bit disappointed in how inconvenient it is. Given that everyone has a case for their phones, you would think that the size of the PHOOZY would accommodate that. However, I always have to take my phone out of the case before I put it in the PHOOZY. Because of that I really don’t use it as much as I’d like. I also don’t use it as much since I can’t see the screen when it’s in the PHOOZY.


            Works great, as long as you have room for it

            I run a lot and bought this to prevent the phone from overheating in the summer and getting too cold in the winter while it's in my hydration pack. Haven't been able to test winter yet, but so far so good for the summer - tested in my car on the passenger seat in broad sunlight, without Phoozy I got excessive heat warnings in minutes but with the case it didn't overheat. Only issue is that it's big, plenty of room for my Pixel 3a but makes it hard to fit in the pockets of my running skirt or hydration pack without some finagling. It's a tight fit in my pockets but does keep the phone from getting sweaty, or wet in the rain, so I do recommend it as long as you have room for it.

            I love it. Granted, I haven't used it in the way I need to yet, I'm excited to be able to go the beach with my phone safely. I can take my canoe/kayak without fear of yet another phone swimming with the fishes! Thank you Phoozy!

            Works great!

            This works great! It kept my phone cool all day out in the sun and didn’t run my battery down. Love this! The only thing I would do different is add a pocket for my glasses.

            Great Case

            I bought it for the summer at the pool to protect my phone.
