I headged on buying the HF tire changer cause of some people having problems scratching rims and haveing a terrable time changing tires. But any way I bought one and used it today for the first time. I wish I had bought one years ago. In less than 5 min I had the bead broke and the old tire off and the new back on with no scratches or dings on the wheel. The machine is simple and does exactly what it is advertised to do. I also used my drive on HF lift. I have had it for 3 years. Nice to work on a bike sitting down. HF might be cheep tools but they sure do work for me.
