My old installer buddy told me he quit using knee kickers on stairs 5 years ago and I thought he was nuts
He said his knees were shot by 48 and switching to a power stretcher and stair tool added maybe 20 minutes a job but he can still walk. I've been kicking stairs for 12 years and now I'm wondering if I'm just being stubborn, how many of you made the switch and did it actually help?
