Moved my daughter from college to college and needed a little extra space. This was inexpensive, but worked perfectly! The straps that came with it were adequate, but I bought the heavy duty ones just in case. It barely moved and we drove about 14 hours so it was a good test. Everything was dry inside and we went through some weather with moisture. It starts out nice and square, but depending on what you have in it, it gets a little distorted by the end of the trip. But as I said, it did not budge.
