good. very good. The force cannot be measured because there is no way to measure it, but it seems to be about 200N or more. Tightening can be finely adjusted over 0~3000rpm at high speed and low speed. Loosen adopts normal speed and short automatic stop function, which is a very useful function to protect the motor from overload. A little heavy is a flaw, but you can be patient enough. It's a good product. I would choose this even compared to Makita. Thanks for the good product.
great tool. IT works very well. im delighted with quality and strength of this tool. Value for money. Self-screws in the board spins well. Recommend for purchase! Thank you to the seller.
