For my purposes as a trial attorney with heavy files it is flimsy difficult to lift in and out of my vehicle difficult to navigate into the courthouse and I fear it will break every time. I had hoped for a sturdy file canvas cart but apparently Staples doesn't even carry those anymore.
I buy one of these every so many years for taking stuff to/from the car. I love how small they fold up - like a briefcase size. The wheels always hold up really well. The plastic eventually starts cracking the side clips break off the handle eventually won't go down anymore - but it can still be used. Once the side clips break I just use a bungie cord to hold it closed when I want to put it away. When the handle finally won't fold back down then I eventually give it away and buy a new one since it takes up more space with the handle up but it's still able to get flat. For what I use them for they probably last me around 5 years or longer so for me they're a good value and like I say someone else can still use it after I'm done with it. Stick it out on the sidewalk with a "free" sign on it and watch it disappear.
This one meets my expectations as a teacher. It was great value after price matching with online price and $10 off coupon. My last one from staples lasted about 5 years. This one Cost me $25.
