Plenty of choice and unfortunately little stability

When I held the little box with the many bits in my hand, I was once thrilled. The box is well organized and the bits are offered clearly. The supplied tool is also good and practical. The first use was also not long in coming, because I had to replace a hard drive in the laptop. This application with common bits have all pretty good shape - is where I noticed right away that the bits that look robust, but would be unable to cope with security a continuous use.
Then I wanted to change the back of a cracked iPhone, I used the T0,8 bit. Carefully screw - no problem! When the first screw screw it also seems all right - The screw was carefully dressed with little strength again. In the second screw then failed the bit the service. The fine tip of the torque bit had so far worn after only one use, that I could not tighten the second screw.
Nail file and put the little bit down a small ground - then it went.

Conclusion: The bit rate only partially convinced. Clear Pro are many different bits, the good organization of the box and secure storage. Toll! Unfortunately, the quality and stability is the (mainly fine) bits only weakly. The material is soft and pretty useless for a professional use. But for the hobbyist it was good enough. Who needs such a tool professionally and permanently, should rather refrain and invest more money!
