      Been using electric weed machine since [@] introduced them years ago. Had a craftsman that lasted several years.Since then, I've purchased 4 machines and returned all but one - the other is just sitting due to several problems. I prefer pump vs self feeding and when ACE ran a special on this particular version I took a chance. Superb machine and easy to assemble. Safe and easy to use. I love it. I would have purchased two but ACE sold out.
