My wife bought me a Roto Zip two years ago. It sat in the case the first six months or so until I discovered how nicely and easily it cut thru about anything. Circles are a snap all you need is a pin hole to put the end of the bar in and spin the saw around. it works great on my stuff. I used it to make round openings for vent fan piping in walls and ceilings etc. was a snap. you'll love it |
