I did not communicate with the store. The device works as in the description. The parcel did not serve, came for a month in the Moscow region. Tested-everything works! Battery and the kit is not included (мизинчиковая)

Good condition

14 Jul 2021

Got it. All working. There is an instruction for Russian for a battery probe. On work a little incomprehensible. When you check the generator (top LEDs), the green lights and flashing red. This is not described in the instructions. When checking the battery charge (medium three LEDs), the average charge LED is yellow and green. When checking the starter current, the LED one and it lights. Starter current keeps the battery-according to the instructions. The device for checking the brake fluid scared-in a glass of water burns the whole line of LEDs. When checking the brake on the car (my old, recently bought, when I changed the brake I do not know), almost all the LEDs burned-I.E. Kapets, we need to change. We need to check the fresh brake.
