Looks good, tried, works. Used to use a regular Kern, and this is kind of a convenient tool

The product in order arrived in good condition, working and appears to be of good quality

On hard metal, you need to press 3 times so that the drill does not slide. It suits me.

Kern's a worker. It is desirable to increase the rigidity of the spring. Recommend

Very good, arrived as described. It is 67 gramas. The are 2 adicional spare parts.
