## Customer Reviews

### ⭐⭐⭐ 







  
  
    Connector low quality
  

*by J***E on Reviewed in the United States on April 28, 2017*

The usb connection on the unit is almost impossible to connect to. I had to look at all the cords I have and find one that was thinner than the rest. The usb CORD connector that came with it is slightly bigger adding to the problem. When connected it is also at a slight angle. I just leave the cord connected because I am afraid of breaking it. I used it once and seems to work. Not something I will use very much.

### ⭐⭐ 







  
  
    it's decent
  

*by D***O on Reviewed in the United States on August 21, 2015*

easy to use for more than one device

### ⭐ 







  
  
    One Star

It only worked twice then it wouldn't charge anymore.
