For us, the HotBend has proven to be reliable and versatile, not to mention portable. I can tell you that we do not miss dragging extension cords and generators all over the state.

Finally, the level of maintenance is very low; I like knowing the tool will work every time; with other types of benders you just never know." -John Burchell Frahler Electric, Tigard, OR NECA Showstopper The majority of problems arise from using a liquid withdrawal, instead of a vapor withdrawal tank.
