I have an old 27" iMac (2009) that won't boot. Although I also have a 2017 27" iMac, I need to retrieve data from my old iMac. So I needed a way to get this computer (during the Christmas season) to an Apple store which is on the second floor of a mall 15 miles away. After looking at many models, I bought the foldable handcart ROY I and am very satisfied. It was easy to set up and easy to connect to a large and fairly heavy iMac. It comes with an extra elastic cord so I can wrap it around the computer to keep it centered on the hand truck. Maneuvering it through the mall and Apple Store crowds was a dream. And when I was done with the handcart, I simply folded it up and put it in the carrying bag that came with it. It's lightweight and easy to carry. When I got to the Apple Store, I found that my computer was too old to be repaired. Since I have to transport it back to one of the places where Apple says Apple can fix it, I'm so glad I have the ROY I foldable cart. It's a great little wagon. See attached pictures.
