Anyone know anything about the Tonnomax roll-up cover?

I think it has bows that provide support/tension and I think the bows stay in place when you roll it up. There are three bows. You probably should verify that. All the pictures I've seen show the bows in place across the bed with the tonno rolled up. (Or is this the tri fold version?) I saw this too but didn't want to post it here because I was not sure which type it was. Roll up looks very similar to the tri fold. http://www.tonnomax.com/tonnomax-soft-lock-rollup-tonneau-cover/#

 

I had something like this on my Silverado and absolutely hated it lol. It's a pain in the ass to roll off and on, it's hard to roll up neatly so you just have a big wad at the top, plus it's not perfectly waterproof and someone can easily open it.
So what's the point of a tonneau cover if it's easily openable to potential theives and water.

That's just my opinion based on why I want a tonneau though
