I bought the product on the market in order to have guarantees. As a result, the battery does not charge and does not work, 4 lights are on . Not the cheapest option. On other sites it is cheaper by 10-15 the result was incorrect. They didn’t even send it to the service, they said to return Sakharov, and demand money from Popov . Here is such a paradox, with these guys you can be left without goods and without money
