This stair climber stands the test. I put so much into this trolley I could hardly believe there was room - but there was. When empty I can lift this unit and easily put it in the car or trunk. I believe that I'll be using this functional little dude for many useful trips when I do any grocery shopping, hauling recycle items, taking items to the Goodwill or perhaps even travelling. BTW, it even is fairly quiet when I take it to the hospital and walk the quiet halls. Really, it's quite a nice purchase especially for the price. I thought I really took a big chance and it would be junky … BUT IT IS nice, durable and hasn't failed me yet.
