It's a tin can with silica gel in it. It's nothing special, but I think it's going to do the job. I think the metal case leaves a bit to be desired. It's thin and cheap, but it does have to bare being put in the oven to recharge. When my wife dropped her phone in the water I actually put this in a ziplock bag w/ her phone, and her phone works fine now. I can't say that this saved the phone, but it didn't hurt.
