I have one. It works great, but it is somewhat slow. When you get one you will want some scrap wood ( 4x4 cut offs ) to use as spacers so you don't have to pump the jack so far each time. One other thing, please stand near the rear while using, a hunk of wood will pop out from time to time and if you're standing to the side well, my only boo-boo so far has been a broken toe.
Mid 70's with heart failure and some range of movement problems following cancer treatment a few years ago and yet another heart attack a few months ago. I can work with this machine for a couple hours at a time.
You may want to set your machine on a couple of log cutoffs, to get it off the ground, it will ease some strain on your back.
Good luck.
Peace
