Review: Not what expected but it definitely does the job - I was expecting just an insert however I got a actual spoiler extender and I was shocked , install was less than 10 minutes if you know what you’re doing and it would help if you read the instructions prior to install, overall it looks crazy good once it’s installed and to my surprise it already grew on my after looking at it for 2 minutes, definitely Vynil wrap it after install , since it does bend you don’t what to reshape after you Vynil wrap.( if you are not willing to to some work for install, then this product is not for you, on the plus side you don’t have to drill or sand the surface it will bend just enough if you let it sit in the sun for 15 minutes)
Review: Don’t waste your money you can go buy something and fabricated and make it look a lot better - The pictures make the product look amazing. Then you spend your money you get your product and it’s a very complicated install even for professionals. There’s a lot of heating a lot of additional attaching that needs to go, and this needs to be notated. Some people wanna add this on, but have the ability to take it back off to make their car stock not have holes in it just saying be upfront and real with people don’t try to manipulate people so you can make your money and leave them stuck with crappy products. Very disappointed.

### ⭐⭐⭐⭐⭐ Great product.
*by J***. on May 3, 2024*

Product is exactly as pictured and described, takes about 15 minutes to install if you know how to use a heat gun and measure the center of a vehicle. words of advice; Use painters tape to mark the center of the spoiler and center of car, use meguiars back to black to make it shiny, take your time and work from the center out. If you don’t get it on your first go it will be fine to take off and try again, but my guess is my more than three attempts and your gonna have to put new double sided adhesive on! Spoiler looks great, highly satisfied.
