I had back surgery a few years ago and as a part time musician hauling amplifiers and other heavy equipment had become a big challenge for me. Many of the places I play have stairs which was another challenge altogether. I already had a regular dolly but that wouldn’t really help me negotiating stairs (some of my equipment is near 70 pounds).I poked around on Amazon and found this one. I ordered the Vevor based on the reviews and the rated weight rating. I have not been disappointed. First, it was easy to assemble and has been very easy on my back negotiating stairs. It folds up nicely and fits in the space behind my seat in my Tacoma. I was initially concerned because it was so lightweight but it has help very well.
