PHOOZY Realtree XP3 Thermal Phone Case - Helps Protect from Sun/Heat, Extends Battery Life, Floats in Water. For 8+/Xr/Xs Max/11/11 Pro Max, S8+/S9+/S10+ and Similar Phones [Marlin Blue - XL Size]

Une protection supplémentaire contre le froid, la chaleur, l'eau et les choc. Mieu que rien, mais ne change pas grand chose pour le prix. Le produit n'est pas étanche, sa ferme avec un Velcro donc à ne pas échapper complètement dans l'eau.Légèrement cher comme produit, mais j'aime mieu l'avoir que ne rien avoir du tout.

Fantastic Color & Keeps my IPhone warm in Winter ❄️ and Safe from over heating in Summer 🌞 when Hot 🥵 outside 👌🏼

I bought this as a Christmas gift. Also it hasn't been that cold outside yet so I'm not 100% sure about the effectiveness of it. The three times we've been outside it did work fine.

Zwar teuer aber sehr gut

I got this because I live in Colorado where we have winter and my employer doesn't allow cellphones at work. I work shifts too. I wanted to keep my phone battery from dying a horrible death, being left in the cold. Esp. now that it's nearly impossible to self-change a phone battery (unless you have a LOT of time on your hands). The reviews I read were nearly all about hot weather protection, and the only cold weather review had the user keeping the phone in his snowboard jacket pocket where he'd presumably contribute some body heat. Sitting in the car at night for 8+ hours in freezing weather, this product does almost nothing to keep my phone from getting cold enough to auto-shut off. I'm talking on a 35 degree night, not even that cold. The only way it helps is if I turn the phone off prior to leaving it, which I wouldn't have expected I'd need to do given that it's 'nasa' type materials. IF I turn the phone off AND put it in the Phoozy AND it's not colder than 5 degrees, then the Phoozy might save me from having to do a factory reset to get my phone operational again. I need to bring the phone in case of driving off the road into a snow drift, but then again, the phone has to be functional. First world problem for sure, but as far as what I wanted this product to do, it's the equivalent of putting on a softshell when there's a blizzard. ***UPDATE: there's a bullet on the product that was not there when I bought it, saying "not intended to be left in cars." Well there you have it. It won't work if you're like me and have no choice but to leave it in your car for 8 hours.
