iPhone 7 Ultra Thin Battery Case, ZgearZ 2400mAh Charger Extender Rechargeable Power Pack. Use This Portable Protective Charging Cover Cases as Backup Power. Includes Tempered Glass Screen Protector

I bought this because I had to replace my apple smart battery case (which worked great but looked trashed) and I was looking for a case that was less bulky in size. I've had it for two months now and it worked solidly for about a month. Now it works intermittently. About once a week it decides to not accept my button presses. It just sits there showing fully charged lights but doesn't actually start charging. Other times it charges great, but then makes a weird static sound when it reaches about 98% until it's fully charged. I still love the size and battery capacity, but I doubt it will have a long lifespan.
