I've tried them twice with very unsatisfactory results both times. Despite having 28 horsepower I apparently didn't have enough power to keep the knives from folding back when I encountered heavy grass. The owner of the company, Roy Megli, tells me the knives won't fold back but that doesn't explain the bush hog like appearance of the lawns when I use MegMos.
They do have a 30 day money back guarantee so if you're not happy with them just send them back.
