Wayne, I had one that looked just like that. I wore it out I guess. It did not hold up in my opinion. The gears that make that thing fold up are plastic. After a while when the plastic wore, it kept trying to fold up while my gear was on it. My stuff actually took a spill more than a few times. The wheels kept folding in. Maybe if there was some way to lock it in the open position.
Now I have one that is just a $20 luggage carrier and it is just as bad! I will keep searching.
