What about the anti-theft device GM90 1GPS installed on motorcycles? Is it useful? Come on, everybody, 3Q.

I happen to be using this burglar alarm, which is very stable on a motorcycle. So far, there are no problems. I remember when I first installed it, the wiring was wrong and the equipment was not working. After asking about their technology, I realized that GM90 1 has the function of "anti-reverse protection", that is, the equipment will not work if it is connected backwards first, unlike some equipment, which can still work if it is connected backwards, which eventually leads to equipment failure faster.
