## Customer Reviews

### ⭐⭐⭐⭐⭐ Well worth the investment
*by H***I on May 13, 2025*

Working perfectly and a rather easy install! Saved me tons of money and kept my vehicle looking great

### ⭐⭐⭐⭐⭐ works great
*by P***I on August 29, 2025*

Ordered this replacement part after my OEM was damaged (Broke going thru car wash). Easy replacement and looks exactly the same. Good price and works great. I also purchased a short replacement antenna.

### ⭐⭐⭐⭐⭐ Fits 2024 Chevy Trailblazer
*by A***  on June 13, 2025*

Very easy to uninstall broken one and replace with new one. Does not come with the actual antenna however the old antenna was salvageable. The base itself was broken. Saved myself hundreds of dollars. I’m a woman who didn’t really know what I was doing and it only took me 20 mins. And I can confirm it fits a 2024 Chevy trailblazer.
