## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good if you have money but other types are as good and less money
  

*by A***I on Reviewed in the United Kingdom on 26 July 2021*

It's good however it's too expensive.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It is very good but it is very big for the trouser pockets
  

*by G***N on Reviewed in the United Kingdom on 15 January 2022*

It has got some good features but you need a big pocket to keep it in

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Quality Case but stops working
  

*by W***K on Reviewed in the United Kingdom on 10 March 2018*

Having given this item a five star rating previously I would now like to add that the case stopped working after eight months and therefore had to purchase another signal blocker to protect my car so therefore probably not worth the money if you can only use for a few months.
