Bought this for at least one job. Its compact design is ideal for such tight spaces. I've researched using the tool and the most important thing I've learned is to take my time with the train. If you rush things, the blade is more likely to break. It comes with a spare blade that I haven't needed yet. It cuts effortlessly through copper as well as plastic pipes. (At the time I was hoping to avoid buying specialized tools). I did my first major pipe repair/replacement myself and it was great. I spent less than $100 on materials and tools and did the job myself.
