I purchase this adjustable shovel to replace my hand shovel when shoveling snow and I have to say that it works remarkably well. I was able to cut my time shoveling by half. Assembling the wheeled snow plow was not difficult and the instructions were very straight forward. The unit comes with two adjustment pins that control the plows direction and the height of the push lever. At first I thought these two adjustment areas would be faulty because of the slack movements but once I started pushing snow these were no longer a concern. I believe it's a great tool to save time and exhaustion.
