Oh yeah, totally agreed on that @matthew_morgan. A buddy of mine loaned me his power stretcher a few years back and my knees felt way less beat up after a long day of carpet work. With a manual one you're constantly pushing down with your legs and it just grinds on your joints after a while. The power version takes that strain off and lets you focus on getting the carpet tight without killing yourself. It's one of those tools where you don't realize how rough the old way is until you try the better option. Have you used one yourself yet or just read about it?
