I am a single keyboard player/singer/entertainer. I've used these carts for years. I'm on my 3rd one. The original was sturdy and well made though a little heavy and sometimes hard to open up. The subsequent ones were lighter and easier to use but the wheels cannot take any abuse at all and I've gone through 2 of them in a little over 2 years (to be fair, I do over 200 shows a year). A few days ago there was a pile of ball bearings on my truck floor and none on one of my front wheels. I'm using the original one until I figure out how to replace the wheel. But these things are pretty great when working properly. They fold into nothing (space-wise) and are light and easy to use.
