BIGFOX Galaxy S9 Plus Battery Case - [New Version] 5200mAh Ultra Slim Portable Charger Case Extended Charging Case Rechargeable Protective Power Case for Samsung Galaxy S9 Plus

This was a Christmas present for my wife. I had to get it replaced and am going to have to return the second one too. It fits nice and looks nice but when we press the power button to charge, it turns on and off. Both cases did this. Rapidly going on and off of charging. That is terrible for the phone battery. Off to find a different brand. Unfortunate because this is one of the better looking ones out there.

Charging went in and out on first use.

I am so extremely dissatisfied with this case. It doesn't hold my phone securely. My phone has fallen out of this case everytime I've tried to use it! It doesn't fully charge my phone. I've tried to give this case a fair chance but no matter what I do it just won't work. Today my phone fell out of the case and my screen cracked. I didn't have this problem with my last battery case. This was absolutely NOT worth the money!

Worst thing I've bought on Amazon. I bought two, and both of them broke almost immediately. The design is horrible and just slides off, it slid off twice as I was walking. Broke my phone, and I can't even return them. Oh, and when it fell the chargers stopped working. Both of them. Total waste of money.
