Pros: Durable frame and wheels, convenient, easy to use, great for people (like me) with health issues who can't carry much and can't use a backpack, no need for grocery bags, holds a lot. Cons: Can be loud when going up steps in a stairwell, confuses some grocery baggers, the drawstring area of the bag breaks down after about a year. I bought a Trolley Dolly Stair Climber, Black Grocery Foldable Cart on Amazon in September 2017. Today is February 5, 2019. My family has used the trolley at least three times a week, every week, in that time. We live near a grocery store and use it to carry groceries home and up the stairs to our second-floor apartment. It's worked wonderfully well for that purpose, and I've had many people stop and ask where I got the Trolley Dolly, as they wanted one, too. I've used the Trolley Dolly to carry large boxes of cat food and cat litter, as well as heavy loads of canned foods, bottled juices and cartons of milk, in all weather - rain, snow, summer heat, day and night. It travels well over pavement, curbs, and up stairs. I had surgery last summer and am not in good physical condition, so sometimes I use the elevator when the load is heavy, but my teenage daughters have no problem taking a full Trolley Dolly up the stairs. I am 5' 9" and the Trolley Dolly handle is high and comfortable for me. My husband is 6' 1" and he feels the handle is a bit low, but it's still comfortable for him to use, even with his back problems. The Trolley Dolly will hold several grocery bags worth of items, if packed well, though of course I don't actually use grocery bags any longer, the cashiers and baggers just put everything directly into the trolley. I think it's worth mentioning that the trolley confuses some people. I've had baggers try to fill it and then put it into my grocery cart, or try to put just a few things in the trolley and the rest in plastic bags. I frequently have to explain that I'm on foot and need everything in the trolley to walk home, or that I have health issues and can't lift the full Trolley Dolly out of a grocery cart, so please don't put it in there. I've also had to ask could they please put the heavy things in the bottom and the light things on top, not the milk on top of the potato chips (this should be a no-brainer but...!). While shopping, I slide the top of the Trolley Dolly in between the handle you'd hold to push the grocery cart and the seat where you'd put a small child. Then I rest the wheels of the Trolley Dolly on the underneath shelf of the grocery cart (that area below the main basket, where you'd put the big bag of dog food or giant pack of TP, right?). The Trolley Dolly fits there perfectly, without taking up any grocery cart space at all, so it's not in my way while shopping. I suppose you could even fold it up and lay it in that underneath area, but I'm not able to bend down and put it there or pull it back out, so I don't do that. All of the photos were taken today, so this is the condition of my Trolley Dolly after about 70 weeks / 16 months of regular use. The frame, handle and wheels are all still in great shape, and the exterior of the bag looks good. It's the interior of the bag, particularly around the drawstring, where it breaks down. I couldn't find any on Amazon, but there are replacement bags available on the company's website.
