I can try and add a bit, but it really depends on what you are looking to use it for.
The mat is made of 3 pieces. one for the cargo area and a for each 3rd seat. Like I said, the cargo mat does not cover the side pocket, it is about the same size as the removable piece that gives access to the compartment underneath the cargo floor. The 3rd piece have cut outs to access the folding mechanisms. They have plugs you can use to plug the access point but I never use them.
Some installation is required. The cargo mat for the 3rd row is velcro'ed (+ screwed if you follow the instructions to the letter) to the back of the 3rd row seat. They stay there semi-permanently (you can always un-velcro them to remove them for cleaning, etc).
This hard to explain but the thing to know about the third row is that the seat hinge/folding location is lower than the rear cargo floor. This is normal but that means that when the seat are up, you only see maybe 3/4 of the back of the seat, the other 1/4 is below the cargo area. So when the seat are up, the 3rd row cargo mat looks like it is the full length of the back of the seat, but when you fold them down, the bottom 1/4 of the seat is exposed. I guess they couldn't make the cover fit underneath the cargo floor when the seat are up. To ensure full coverage with the seat down, the cargo piece as a flap that covers that area when the seat are down and folds up and rest against the back of the seat when they are up. That flap is just rubber so it sometimes fall down in the cargo area or doesn't really fold back down when you fold the seat. This is annoying but really just a minor annoyance since you usually just throw stuff on top of it after anyway which puts it back down in place. It also is a little bit in the way of the folding mechanism for the 3r row, you kind of have to move it out of the way slightly to pull the handle fully, but it is not hard. (You can see what I mean on the photo with the 3rd row up on the link i provided.)
I think it works well for general dirt protection, but wouldn't be great for large spills. There is a channel all around but it doesn't really have a lip that would contain water. There are also multiple leak path such has the cutout for the folding mechanism, the space between the 2 x seats and where the trunk portion overlaps the 3rd row seat. So not great for water related protection.
But, you can leave it in place at all time with any configuration (2 x seat up, 2 x seat down, 1 seat up, etc.)
So bottom line of my reviews
Pros:
- thick solid rubber
- is always on and work regardless of the seat configuration
- Not slippery at all (prevent items from sliding)
Cons
- Not good against large spills
- flap is a bit annoying
- require installation (but fairly simple installation).
- it is not cheap
- Not slippery at all (not great to retrieve heavy items all the way against the 2nd row)
-Does not cover the side pocket (or is it a good: still allow access to the side pocket under compartment? )
With all that though, the best protection is the protection that is there when you need it. There is no point in having the most waterproof cargo mat if it is sitting in your garage because you had to use the 3rd row the day before. And you don't have the issue of having to fill up all your cargo space with a rolled up cargo tray if you need to use the 3rd for an impromptu family members joining you at the last minute on a trip somewhere. I guess it depends on your need
P.S. many users have reported that the installation works fine with the velcro only and without the screws. The screws just hold the velcro more securely. I ended up putting them in because when I slide heavy items on top of the cargo tray I was afraid the velcro wouldn't hold up.
