I was impressed at first. It turned out that the quality corresponds to the price. I was intrigued by the one with the cartridge. Holds short bits in the chuck so they don't get caught in the holder when you pull out the screwdriver. I put it in my drill, turned it on and everything flexed. I checked several times that it was sitting straight in my drill chuck, and no. Big swing. Spring. Later we will see how the rest will look like.
