## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Not easy to keep on cat flap
  

*by A***R on Reviewed in the United Kingdom on 28 November 2023*

Keeps falling off as too small for wall opening

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fixed easy and snap together
  

*by J***S on Reviewed in the United Kingdom on 15 February 2023*

Just click and go. Easy to fit push together and very strong.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Measure carefully!
  

*by R***R on Reviewed in the United Kingdom on 20 July 2015*

These work well but you may find you need more than you think!  Measure the depth carefully and allow for 5mm to protrude each end.  You do have to follow the instructions and glue these, other wise they detach just at the wrong moment.  Bit flimsy so only 4 stars.
