I thought for a long time whether it was worth installing additional equipment to protect against theft. I bought a mechanical steering wheel lock and an alarm with a GSM module after reading reviews

I know that if they even try to steal the car, it will immediately be blocked, and I will receive a notification on my phone. Of course, this is not a panacea, but it still helps me feel more confident. In the conditions of the city, where thieves are not asleep, such things are really necessary.
