A part of the review has been auto-translated.
This is a very compact set and well-engineered. Holder spring-loaded inside protective aluminum case. Total of 21 bits plus an extension and small driver handle. The bit quality is very good with tapered shafts for the smaller bits (all 1/4-inch size base). All the bits are held in place with magnets, so sometimes you can pull another out accidentally, so a little care is needed selecting the required bit. Nice to see a light oiling on the bits, so surface rust should be delayed for a while. Laser etching a little feint on the tool steel bits and the handle is really small, so this set is only for low-torque, lightweight jobs - but you could use any of the bits in a standard 1/4-inch screwdriver if needed. I like that this set uses standard sized 1/4-inch bits and is very compact. Can recommend it for anyone looking for a compact screwdriver set for light duty/occasional use.
Much better than I expected! Excellent quality product for a fair price.
