Sehr gute Aufsätze. Robust und einfach zu bedienen.

Good well made but only comes in one size, these would be great if they came in the 3 socket sizes

Excellent

Good value but the solid single pieces are imposible to use with hands only, way too tight to get bit in and out easily.The slide and lock one has too much play once bit is in.

Poor quality.... I've broken new bits because this will not hold in position and slips down causing the bits to brake.
