"Saw this at the Screwfix show in Farnborough and thought it looked impressive. I had already used the 40mm waste version but not the 15 & 22mm versions. This set makes cutting plastic pipe so much easier, without any burrs or mess. Really, you have to use it to realise how much better it is. I fit bathrooms for a living so I have a lot of experience with plastic tube. The 15 & 22mm cutters are way better than the scissor action cutters and you can get into tighter spaces with them too."
