First. I'm not sure if Makita knows they have this set. Everything in the case is Chinese consumer goods with below average quality. I compared the bits from the set with those that are on the tables in the market. THE SAME. The flexible extension even has the same notch for holding with the market one. EVERYTHING IS THE SAME. A plastic level is something. In the flash, unscrewed by the "propeller" and this is Makita ? Jagged drill bits from a sealed case. I checked the kits in different reputable stores, the quality problems are the same everywhere. They took a case, put cheap china there, wrote on top of the MAKITA case and voila, a set of cats. I read rave reviews and wonder, guys, are you guys at all? Do you work with your hands? Or do you open this "miracle" and feel your coolness from owning a "professional" MAKITA set? This is a cheap craft, alas, marketing is merciless even to the masters. For the home, sometimes unscrewing something, or twisting it will do. Loads, even of medium intensity, are CONTRAINDICATED for this set! Long bits do not have angular rigidity, quickly turn their necks, drills become blunt instantly. In the kit, everything that could be replaced has already been replaced. Sad set. I do not recommend
