## Customer Reviews

### ⭐ Wasted money
*by L***O on March 17, 2020*

Sensors sometimes works and sometimes not. I noticed the vehicles next to the sensors and never gave me an accurate reading. Sometimes i have a vehicle on the right side and left sensor light up or vise versa. I change wires connector positions but still have the same issues. Not Recommended

### ⭐⭐⭐⭐⭐ great project, not for beginners
*by K***A on May 7, 2020*

THIS IS NOT A BEGINNER FRIENDLY. This is an all day project, but when done correctly they work great! Yes, the instructions are very short but if you understand cars and wiring it can be done. I recommend taking apart the car pieces to fully integrate the system, it will look the best. Lay everything out and take everything apart, then start plugging everything in and drilling the holes. The sensors are sensitive, but if you follow the directions and put them in the right place, they work amazing. Would definitely buy again. For reference, this was installed on a 2008 Jeep Liberty Sport in about 4-5 hours.

### ⭐ Not worth the purchase
*by M***T on May 27, 2022*

The sensors has an angle on it that no matter what position I put the sensor at it sometimes picks up an object and other times it does not. I asked support about what angle to put sensor but answer is not clear.The warning indicators tape on backside does not stick to car, tape is weak and indicators will fall off.No volume adjustment on Audible buzzer.
