  • Perfect look
Color: Carbon
Works nice on my mazda 3. Looks really good. Must try!! Will buy again because my brother wants for his car too.

  • Good value
Color: Black
For the price you pay it makes the car look much prettier and will do you well. It may just be some hard plastic but if they ever flew off you would probably want them to be plastic. Easy to apply and worth the purchase.

  • Flashy addition
Color: Bumper Diffuser Red
I have theses mounted on a Jeep Compass. Added just the right accents to rather plain fascia’s. Don’t know if they serve any function other than decoration!

  • Questions still about long-term use
Color: Carbon
Should have used 3M double sided tape instead or a no name product. Seems to adhere well after two power car washes. No noticeable difference in wind noise or stability of car in cross winds or airflow over rear of car.

  • Look great! Sun fade like crazy though
Color: carbon pattern
I’ve had these on my car for a year the first one fell off like 5 months in rest of the sticky wouldn’t come off. And they sun fade so bad

  • Eliminated 90% of wind noise between truck and topper
Color: Black
Put 10 on in pairs, equal distance apart, on the backend of the cab of my pickup truck. Back 2 inches apart, front slightly turned towards each other. Put a drop of super glue on each end to make sure they stay on. Before this the wind buffetting noise between the cab and topper were so loud I couldn't hear the radio. 90% of that is gone now. Cheap, easy fix. ... show more

  • You get exactly what you pay for
Color: carbon pattern
The outcome of my car turned out far better than I was hoping for. 5 stars so far for ease of installation, the adhesive seems to be pretty strong so far. I love the profile and I love the carbon fiber pattern. All in all great buy, would definitely recommend to a car enthusiast
