I've been lurking and watching this thread for a couple of weeks as I had my first android phone, Galaxy S6, on order. It has arrived and I'm quickly trying to figure out what case I'm going to get. I'm thinking about Neo Hybrid Metal. Can anyone offer an opinion on how easily that case comes on and off? I ask because I'll be using the phone in an arm band for running and those usually fit pretty tight so I'm thinking I will have to be able to take the case off relatively easily. If the Neo Hybrid Metal is tricky to get off often, or will wear out if I do that to it, I'll go with the Spigen Ultra Rugged Soft Shell which should pop off and on pretty easily. TIA!
