### ⭐ it broke my phone!!
            
*by L***N on January 15, 2019*

this charger may look cute, but don't let that catch your eyes, i got it in the mail the other day and used at first it was great! it charged quickly, looked cute, and no useage of a cored.. well thats what i bought it for but after about a week my phone just turned off and I had to go to the apple store to get it fixed and the apple store said that the problem was the charger phone case, so I personally don't recommend this because it may cause the same problems like me.
  

### ⭐ ❌🚫🛑DO NOT BY THIS PRODUCT DO NOT⁉️‼️
            
*by A***R on December 20, 2018*

This product sucks doesn’t come off easily doesn’t charge for that long stopped working in a month very durable though and cute but the battery sucks barely charges for one day and takes forever to charge the battery at all to get 100% charge dies really fast and I broke it trying to get the case off my phone!
  

### ⭐⭐⭐⭐⭐ Nice Battery Case!
            
*by B***N on October 24, 2018*

I bought this battery case for my wife and she loves it!  This battery case is slim and does not add too much weight to the iPhone, especially compared to the heavy old battery case she used.Placing and removing the iPhone from the battery case is easy.  I love that the top detachable part is magnetic and you can angle it as a viewing stand if you stick it on the back of the case.It also charges the iPhone to full 100% so she does not need to constantly bring around a charger.  Highly recommended!
