I got this mainly to save my back when lifting heavy things from my car (I have a home business). One of the key features I I liked as an option has become very important - Connection to my riding lawn mower. The first time I used it, I had about 600 pounds on it. I began to pull it and I felt the strain on my back wasn't much different than lifting the items. Got my "tractor" and there was a very quick change in the handle and away I went. It is very easy to pull on hard surfaces, but I was pulling across grass too.
Easy to assemble. Lowering of the sides is a great option as well. I researched many carts, and this one kept coming to the top. I am very pleased with it so far.
