For its price, it is simply perfect.
It does not give false alarms.
Easy to install.
It does not have a 6-tone siren, even though it claims to.
Powerful siren.
Very nice controllers.

I bought 4 for the family cars. I don't think I would choose it again. You unlock the car with the key, get in, sit down, and get out without hitting anything. Unless you hit the door on your way out.
P.S. The lights were in the photo, but not in the box. They are extra and cost 18 each.

For now, very satisfied. Lifetime warranty. The box with the antenna is placed in front and below the windshield. And it has such a powerful blue LED light that in the dark I can find the car from 50 meters away. It also lights up the wall next to it! I don't know if it needs to be so powerful, but I like it. The buttons cannot be pressed in the pocket. I would like the keychain to be more visible. I have also requested an additional radar inside the car. Now with the rain, we will see how it will work.
