I had the hose clamp and an old dog leash that I could use to do it with, so it cost me nothing. I sewed the doubled up strap together to make a couple of different hand holds like in the thing they used. I'm still getting used to it but it was both faster and easier on the back than shoveling without it. You can throw the snow farther out of the way, too. It's a fairly light snow here today but if you don't try to move mountains at a time I'm sure it works on heavier snow too.
Figure if it saves one other person's back it would be worth posting it.
