I have read reviews that it does not bend under load. I use it to move printers, my real complaint about the cart is that the floor you put items on is very short. I wish it was bigger to place items more safely. You can't just use the handle to tip it back onto the wheels if the item is heavy. It will bend or break. I replaced the bungee cord with a strap and tied it from the metal base to the handle. This will keep the item from bouncing and the strap will help tilt it backwards rather than all the weight on the bottom. This works for me as I mostly need to ship toner. I will use it for small/medium sized printers but for something larger I use a different carriage. nice for the price.
