I purchased this after my 5 year old one broke trying to carry too much of a load. Even though the wheels are not as big as my last one, it still does the job. If you have never had a 3 wheeled cart, then you are missing out. Go up and down steps and door thesholds with ease. The extra 4 wheels that can be added on the bottom are great when you need to wheel cartons around. Sturdy and lightweight
