Good tester precision meter

It works perfectly

11 days to Ukraine. I have already checked both the battery and the generator, everything seems correct. It's necessary to have such an inexpensive device in the car. Thank you to the seller.

Fast shipping, useful battery status testing tool.

It looks very good ☺️

Everything is fine, but I need to test it better for a longer time. However, it has proven to be a practical tool for knowing if the battery is charged.
