Hi ..I can across your page and have had a Wovel for a couple years and havent hurt my back clearing since.. think about lifting with a seasaw. I dont have the folding frame version and that would be nice rather than just hanging it on the wall in the summer. I did alot of searching on sites that talked about it but there is more out now...and alot of reviews on Amazon it seems.. anyway,it cut the clearing time down probably by half and I just never get to that exhausted or really fatigued point, so I am a big fan ...if that helps.
