## Customer Reviews

### ⭐ 1.0 out of 5 stars







  
  
    bad design
  

*by D***S on Reviewed in the United Kingdom 🇬🇧 on 13 November 2021*

the black rubber seal at either end of the union fits in a slot that goes all the way through the plastic part meaning there is only a small joint of plastic at both top edge's you have to be very careful connecting it as it snaps easily as mine did and now leaks, at some point i will replace the guttering and will not be using Osma.

    A piece of guttering.
  

*by S***R on Reviewed in the United Kingdom 🇬🇧 on 13 April 2013*

What's there to say? It's a piece of white guttering that does what guttering does in an aesthetically neutral sort of way.
