Overall I like their guards especially their front guards. But for me, I don't quite like their rears due to bottom bracket design. It damaged the clear coat where bracket touches underneath the bumper.
I had FX3D rock guards but will be ordering some Megachip guards to replace. I heard high wall OEM mats have velcro on on the bottom side which some people dislike due to possibly damaging carpet where velcro attaches.
I think the lower hole where the bracket goes in should be angled like this one in the photo. The photo in the instruction was confusing because it shows the bracket is angled even though the bracket and the lower hole is 180° horizontally straight on mine.
For those who have fx3d rock guards 3.1 version, how do you manage to sit rear brackets aligned perfectly on the bumper underneath where bottom screw is? Our bumper that area is angled but the brackets are horizontal where put in the guards.
Make sure to have your salesperson take some hi-res photos when your car unloads from the truck especially since they are the one handling all the transport to your place.
