    Case doesn’t hold
  

*by M***5 on Reviewed in the United States on March 4, 2019*

The case fell apart in less than 1 week of using,,,,, really bad quality,,, I guess I paid for what I got

### ⭐ 







  
  
    Should have taken previous reviews seriously!
  

*by J***K on Reviewed in the United States on July 20, 2019*

Within the first day or use, the finish on this product began to disappear.  By the end of the week there were multiple places the finish was missing.  Within 3 months of gentle use (mostly sat on my desk), the top of the case would not remain in place.  What a waste!  No warranty ~ just threw this dysfunctional product in the garbage.

### ⭐⭐⭐⭐⭐ 







  
  
    Worth the extra bulk
  

*by A***A on Reviewed in the United States on March 26, 2019*

Seems to charge the phone just fine - there’s a trade off of bulk and convience. Can’t have both.... used it for a recent trip to DisneyWorld and it easily kept the phone charged ALL day (heavy use of video/pics) and cell data. Would recommend.
