"It is difficult to review an item that is so remarkable in so many way, but as Screfix want endorsments, here goes.. The colour is white which remarkably, matches the rest of the white guttering perfectly. Although no instructions were included, such was the simplicity of design that I had no trouble fitting it. Features are many - it is white with contrasting black rubber inserts, made of plastic and rubber, easy to carry, fit for purpose, I could go on and on. Performance and reliability are harder to judge, but if I'm still around in 20 years time and Screwfix still want people to review absolutley everything they sell, I'll be happy to give an update. Watch this space !!"
