Just installed , very nice cover. Heavy duty and looks great on truck. It came damaged, but they were very quick getting it replaced.

The Revolver X4S is just what I needed. I have a bed rack for my Tacoma and I want a hard cover that locks shut, and still had the ability to open it up when the bed rack was still on. It opens and closes very smoothly. I did my research before hand to make sure I had the correct brackets for my bed rack that was compatible with the Revolver X4S. It was a very straight forward install with a few adjustments to get the tonneau cover rails tight against the sides. I love the flush looks with matte black color. The Revolver X4S took all the possible problems from the X2 and upgraded them. This is a big winner for my application.

After TONS of research I decided to get this RetraxPRO XR, and I LOVE IT!
Worth every dime!

The Retraxpro XR is built like it was designed to keep your items safe as a bunker in a nuclear war. This thing is tough but smooth and easy to use. I have an 8ft bed on a 2023 F350 and so far no dust no water no prying eyes. This product is an excellent option for keeping a utility knife from being the only tool needed to cut through a Tonneau cover and so easy to use that you hardly need to have a brain to operate. If you think it’s pricey ask yourself, “what’s the price of protection from an atomic bomb”, buy a truck bed bunker, buy a Retrax.

I bought this to replace an aging Extang Revolution. I loved that cover mostly because I don't like covers that have velcro to seal the sides.
This cover does not use velcro. I love the very low profile and the ease of rolling. I also like the easy close at the tailgate. The Extang had springs and needed to be stretched to close it. The mechanism eventually fails and it becomes hard if not impossible to get it closed and latched.

I really like the weather resistance of the X4S. So far I've only seen small amounts of water in the truck bed after rain storms.

The negatives on the X4S, at least for me, are 1) the knobs that hold the head of the cover at the front of the bed have nylock nuts in them and they are VERY hard to tighten up, despite the knobs. I may change them to standard nuts and lock washers. 2) The hold open straps now have this sort of T connector that slips into a holder and is supposed to stay put once you tighten the strap. So far, I've seen the straps loosen on there own and the T connector is in danger of falling out. I'm trying to figure out a better method of securing the cover when it's open. But some have said this in an improvement over the X4, but I don't really buy that.
