Of course, for such a price, with such seductive technical characteristics, it was to be expected that the build quality would not be a fountain, but the backlash is already very strong even in comparison with other Chinese counterparts. Soft start is very smooth - it picks up speed very slowly. For normal operation, you will have to "finish", obviously with a loss of warranty. So, those who prefer to buy a tool to work, and not bring it to mind, should look at more expensive models. In general, the price corresponds to the quality and there are no particular regrets yet). I am writing a review because there were no reviews at the time of ordering and it was annoying.
