Two of my trucks have come with roll-up tonneaus similar to that LoPro (but I don't know the brands). they don't work for me because I need to be able to carry my dogs in the back, which dictates a cab-high topper. But for the couple of weeks that I had each of them I thought they seemed like a pretty good option. They seemed to keep the inside of the bed dry and were pretty easy to roll up or to roll back out.
