The material is very sturdy and came rolled up. Left it on the kitchen counter for a week with weight on it to get it close to flat. When installing there are about 3 predrilled holes in the mat. You have to drill into the floor board to install provided clips which is fine, but I had extra clips so I drilled additional holes in both sides to get the malt flush. I like the mats.

Fit perfectly!

The only complaint was they are shipped rolled up. Have to let them set out in the sun all day to flatten out. They're not rubber! More like a WeatherTech floor mats in a vehicle. Had plastic rivets to mount them to the floor, but wasn't drilling holes in a brand new buggy......

I was kind of skeptical to purchase this grille but ended up pulling the trigger on it , installation was not that hard, the hardest part is to swap the camera attachment to the non camera one , after that everything was a breeze, looks great and the material quality is no different from oem, will do another review after couple of months to give more info on the durability and paint fading ( if there’s any, hope not)

Another great Amazon buy. Don't let the price or the crazy brand name keep you away. When I took the OEM grill off and compared it to this, it was pretty much spot on. All the clips are located in the right place, fits nice & snug and looks great. The most trouble I had was figuring out how to insert the front camera delete. There are no directions or videos explaining it. Once I concluded there's only one logical direction, I held my breath and applied the force that was needed to snap it into place. After that, it was a breeze (thanks to an unaffiliated YouTube video). Time will tell if it holds up (didn't like the other review that showed paint feeling off after a few weeks; not sure what that's about). If mine does the same, I'll surely update my review. For now, Highly Recommended.
