I lost a couple of screwdriver bits, I could not buy separately. Some pros: I have been using for 5-6 years. Like a household tool. Satisfied. The quality is commensurate with the price. Packing saturation. Case, metal stutters, strong, reliable and fixes the tool well. With its cons: I worked on the street, water got in (there was a light rain, I didn’t pay attention), blackened bits instantly covered with rust. The seals fall out of the bottom of the heads. The screwdriver handle moves along the guide pin with a vertical force.
