Review on 🔍 Ultimate Detection Power: Hardwired Valentine Beltronics Detector (Inline) by Josh Maher

I bought for my Mazda CX-9. I connected everything correctly, but it didn't work. The seller sent me a new one. The second didn't work either. As this was my first time installing such a product I figured it was my own incompetence or maybe I bought the wrong part. After hours of troubleshooting and installation, the wires broke. I gave up this project. I then spent several hours and more money running a long extension cord from my radar detector to a 12v outlet connected to the fuse box. It worked, but it looked ugly. Not satisfied, a month later I bought a similar mirror wiring from another seller. It worked right away. I installed correctly at first but received two defective items from this seller. I didn't want to try a third time. Bottom Line: It's an easy install made difficult/impossible by a faulty product.
