We keep one at home and another in the car because we never know when we might need it. We haul stuff over city streets and sidewalks as well as indoors from lobby to apt. They do wear out--the handle mechanism can stick or the flanges/clips break--eventually. One previous model has reinforcing sliders along the top edge while the latest version purchased has the old-style edge stabilizer clips stored in the base--not nearly as convenient. But still the best and easiest to deploy. Happily the price hasn't changed much in decades.
Pros: It’s roomy enough for my needs. It rolls well on pavement. It’s lightweight for me to handle. The price was good. Cons: it would be better with 4 spinning wheels.
The bottom clips don't seem to always stay together but it hasn't caused an issue yet when I have it loaded up and the wheels are durable and roll smoothly.
I rely on this cart to carry heavy things to and from my car including books cases of seltzer pounds of produce and items to be donated. No more back-breaking trips. I recommend this cart to everyone commenting on the contents.
