## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Not what they say (or show)
  

*by T***B on Reviewed in the United Kingdom on 27 September 2013*

The eyepiece arrived on time; so far so good; unfortunately, it was not the one that was advertised on the Amazon site and did not contain what they said it would. Don't get me wrong, the product is fine, but it would be nice if the photograph and the description of the product were EXACTLY the same as the product that arrived. If there are problems, just send an email and let ME decide, not Amazon, probably there is some law somewhere about trade descriptions, Amazon would do well to read it and not just expect customers to send the item back; waste of time and money for everyone.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    No cleaning cloth.
