It took me a minute to figure out exactly how to use it. I overtightened it on the pipes and then didn't have the strength to turn it to cut the pipe. It may not be a problem for others, but it is for me. I found that if I tightened it enough that I could still turn it, made a full turn on the tube and then tightened it again, everything worked perfectly. Very clean edges although I removed the old baseboard heater pipes so didn't bother me.
