## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for the Price!
*by M***S on December 28, 2020*

Pros:Great battery lifeNot Over-sized (depending on the person.)Works as intended for iphone 11 Pro-maxUses Lightning port to charge (no extra cables needed to be purchasedCharges both phone and case at the same timeCons:Takes awhile to charge phone in or outDecently heavyDoes not protect front of phoneIf you are wanting to buy this for yourself or a friend its definitively a good buy. Good for people who forget to charge their phone or are unable to find an outlet at work or out and about. would not recommend using for fitness or anything athletic unless ur setting up a speaker in a gym.

### ⭐ Stops Working
*by M***B on December 24, 2022*

I’ve bought this case three times. I replaced the first one after two years because the battery life wasn’t as good as it used to be. The second case stopped working altogether after a month and wouldn’t turn on or allow the phone to be charged. I bought a third case which also had an issue. When this case was unplugged from charging, it would turn off and wouldn’t charge the phone. Basically it was just a bulky case with no battery. The case itself is good but the pieces are defective now and don’t work so I’m not buying it again. I’ve bought a different charging case now which works better.

### ⭐⭐⭐⭐⭐ Don’t waste money on this garbage
*by L***H on December 19, 2020*

Not with the money. Purchased in July and stopped working in October. Worked great at first but now just Blinking only on first light which means it is not taking in a charge to charge my phone when needed. Expensive phone case for nothing. Garbage!
