I have had them in 3 of my trucks and i have a love/hate relationship with them. Current vehicle is the 2013 lt tahoe and i have the oem floor mats on top of the lloyds. I find carpeted mats much more appealing, comfortable and better looking then plasticy(if thats a word)/rubbery catchall mats. They cover entire carpet area of all footwells but remember if u spill something there is no lip and that will eventually get to the carpet.
Love:
Fronts-stay put, comes with plastic screw to hold in place, cover entire carpet area, color matches perfectly and are nice and plush on your feet.
Backs-cover entire carpet and are plush on your feet color perfect
3rd row-covers carpet, color perfect,
plush on feet.
Hate:
Fronts- nothing
Backs- move around too much, i am constantly pulling it toward the passenger side to cover carpet
3rd row- stays good but moves alittle
Now that being said, i have 3 kids that jump in, cross over and move around alot, is it them? I dont know. When they were small in carseats in my 2001 tahoe i was moving the mats constantly also so i dont know. I can post pics if u want. My 2 cents, yet again.
