## Customer Reviews

### ⭐ 







  
  
    DOES NOT FIT - do not order unless you can fit it immediately - right label, wrong product
  

*by T***M on Reviewed in the United Kingdom on 24 November 2016*

Beware - don't order these if you are not going to use immediately - when you open it and find that you have received the wrong product labelled as the right one, and it doesn't fit, you will not get your money back if you don't notice the error until after the 30 day period has expired.  Clever scheme!.
