Review on 📱 360° Rotatable Premium Sports Running Armband: iPhone 12, 12 Pro Max, Samsung Galaxy S20, LG, HTC, Pixel & More - Universal Cellphone Holder + Free Extender Strap by Jeff Labore

Overall I am happy with this product although I have only been using it for about 10 days. Not sure about long term usage which may depend on your application. I mainly use it for cycling. I found it fits my hands well and provides easy access to the phone, but I see other people saying it won't stay in their hands. I wonder if this has something to do with the shape of your biceps. It also allows you to rotate the phone easily, which I haven't used much, but I can see that it comes in handy. I found the elastic rubber held up well, but the phone needs to be held HERE so the straps are definitely stretched. It holds up well, but I suspect the straps will end up being the game changer. If I can hold out for a few months I will be happy. I don't expect it to last forever, at least not with this design. I bought another arm mount to try, more akin to a 'pocket' that will obviously last longer, but doesn't provide easy access to the phone as it's hidden in the pocket. So you decide what design you want, whether you want quick and easy access to your phone or need long-term durability.
