We have used this shovel quite a few times this winter. It does reduce back strain and what I really like, is the ability to fling the snow farther away with ease. The only problem is we only have one, and two people usually doing the shoveling. We will be purchasing a second one in the near future.
I had back surgery two summers ago and last winter was misery; but this winter I actually enjoyed getting outside with my new Snow Joe snow shovel. This thing is worth its weight in gold.
I liked this shovel so much I bought a second one!!! Easy on your body, especially on the back and makes shoveling much easier than a regular shovel. I especially like the two handle system. Very sturdy. Highly recommended, and I have already had a lot of practice with it this winter.
