The device is working properly. My car is little used in winter, when I tried to start my car for a few days, as it was very chilly, went nothing more. That was me in the last few years in winter often like that. I always had to ask other motorists to jumpstart. Sometimes I have to wade a while until someone came. Now I have this great jump start that my car brought great to start. I am thrilled and this device can really recommend it. I have a Toyota Yaris, the battery is no longer the youngest. My car started immediately.
