I got the tonno pro lo roll. I really like the look, it's low profile, blends in perfect and looks great since both it and my Ram are black.
Since installing it I have removed it twice to haul cargo, so I have gone through the install and removal process a couple times. It's easy now and probably takes 5-6 minutes to completely remove and about 10- ish to re-install.
Above is the good news and I want to make it clear I am happy with it.
However.... The initial install didn't go as smooth as I expected. Main reason, the material is very tight out of the box, unforgiving and basically won't stretch. The instructions say to open it up and let it sit in the sun. I did this on a 75 ish california day, not cold, but not hot.
I followed the instructions and mounted the cover to it's mounting rails (at this point it's now rolled up), I then put on the brackets and mounted the rails to the bed. At this point you roll out the cover and latch it at the bed.... There was a 0.0% chance I could latch it, it was waaaaaay to tight and every time I tried to muscle it to get that first initial close.... The rails would come off the bed mounts due to the pressure I needed to try and close it.
Long story short, how did I solve this initial.... Stretch....close....latch.... Issue.... I put the cover mounted to its rails on my grass and to get it to stretch enough to close the first time, I literally had to step on it with my weight. Once I did this I rolled it back up, re mounted it to the bed, rolled it out and it latched fine.
Hope this helps someone
