The screwdriver was purchased mainly as an electric drive for winter fishing. He does his job brilliantly. I use it in tandem with the Hong Kong drill Tornado-M2 of right rotation, the adapter for the ice drill produced by TekhnoMaster LLC (Hong Kong) and the Terniks bag-mitten (Hong Kong): one 5A / h battery is enough for about 90 holes 130- m auger at an air temperature of about -15, with an ice thickness of about 25-30cm. In more difficult conditions, I have not yet had a chance to test it, but, given that two batteries are included in the kit, I have no doubts about the positive result)) I am satisfied with the purchase. I recommend. As for the price, it's all relative.
