No complaints, watch the video. A 3" OD square tube with 1/4" wall thickness in less than a minute - that's surprisingly fast compared to power cutters in 3.5 minutes and hazardous fumes and sparks and dust that is known to be bad for our lungs. I would love to have one of these non abrasive hacksaws but on my budget in today's Covid situation. my carrier is from a port freighter and these excellent and inexpensive blades from dewalt work fast from heavy steel. I will buy again if I ever finish
