If you type a Chinese instrument in parts, then it will most likely be more expensive. So this set is a good choice for the home, if you don't need to work a lot and often with this tool. But there will be no headache about the fact that some kind of bit or drill is missing when they are needed. Pros: Convenient, securely closing case, a lot of things at once in the kit. The most common bits come as a set, so if they break, you do not need to immediately look for a replacement. Rubber holders with bits, if desired, can be easily removed if it is not possible to take the entire set with you. Cons: This is China, no matter how you look at it. This applies to everything - the quality of the metal of drills, bits, the diameter pattern has nothing to do with reality. In my set, the core is not symmetrical, so when corening, you will need to carefully look where it stands. In platypuses, when opening and closing, a part of the metal near the axis chipped off, this was not even the case with FIT. The transparent polycarbonate wall in the case apparently plays the role of a "showcase" of the contents, but in reality it will quickly break. Knife - without a screw blade lock, when cutting, the blade falls into the handle.
