"I bought this at the start of a diy job to remove one radiator and install another in a different place. I made a total of around 20 cuts in 15mm and 22mm copper pipe. However after less than half of those I had to use a pair of pliers to tighten the blade during the cut as it had become blunt. Though it still made clean cuts.
For the convenience of use it's excellent, and takes a lot of effort out of cutting pipes in tight spaces with a hack saw."
