I have used one of these for years. So easy to fold flat for the trunk of the car. I gave one to my brother and one to my mother. I use it to move groceries into the house from the car and to transport items from house to car or from one room to another.
This is the best cart of transporting groceries into the house hauling bags of garden soil and bags of landscape rocks. Pretty durable but you do need to guide the cart down steps to avoid undue stress on the cart. I've had several over the past decade that I have worn out but I haven't found a better cart for the money.
We use many of these in various ways for business. We like the slightly larger capacity taller height. The new flip-over locking latch mechanism is better then the previous sliding one. The material though of the overall crate is not as sturdy as the previous model. The sides bend/flex and is otherwise flimsier then the previous one. You can tell that a different manufacturer was sourced for these. If the best of both can be combined into one unit it would be the "perfect" foldable rolling crate!
