So I have got my son numerous of these phone case Chargers. So far none of them have held up to this one. Honestly this one has actually lasted the longest and its still working. That's the biggest thing. Other ones that we have gotten maybe only lasted couple weeks and then they just wouldn't hold a charge. My son uses this one all the time he even puts it in his dry box in his four-wheeler and drives around with it all over the place and it still works. My son is not gentle on things so this one gets an A plus in my book it is a very good product would recommend to anyone.
