    Battery life could be better
  

*by J***3 on Reviewed in the United States on June 16, 2022*

My husband purchased this to replace the Apple Case he has had for over two years. It works but the battery is not the greatest, but I get that with buying a cheaper product. He still uses it from time to time. I do recommend the case though.

### ⭐ 1.0 out of 5 stars







  
  
    Useless.
  

*by I***5 on Reviewed in the United States on December 27, 2023*

Barely any charge just use this as a case

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Amazing build Quality
  

*by M***L on Reviewed in the United States on May 23, 2020*

This case is so amazing. First let me start off with the build quality since that’s always a big thing. I normally have LifeProof cases or OtterBoxes on my phones since I’m a bit clumsy but this didn’t disappoint because the build quality felt just like my other OtterBox case which is insane.Next thing is the battery life, I have an iPhone X so this thing charged my phone fully about 3-4 times without having to be charged itself so I never had to stress about finding a wall outlet to charge my phone, just turn on the case and I’m good to go.If you are thinking about buying this case you most definitely should.
