Does the job,
Verified Purchase(What's this?)
This review is from: Wagan EL2456 Wireless Rear Backup Safety Sensor (Misc.)
I bought and installed this mainly for my wife. It does what it says, but it lags a little. It takes a a second before it starts to register. And sometimes if you are in reverse too long, it stops registering.
All in all I am glad I installed this on the car. It is accurate in measurement but like I said, you must be backing up at idle for it to be accurate because it takes a second for it to catch up.
