    Jó minőség bár némelyik belül egy kicsit sorjás, ami nem zavaró.

    Die Wellenkupplung für Schrittmotoren ist eine bessere alternative als eine starre Verbindung. Der Schrittmotor wird geschont. The shaft coupling for stepping motors is a better alternative than a rigid connection. The stepping motor is spared.

    Received in good order and fast. The couplings fit well. (I ordered 3; they come per piece.) There is however a disadvantage: the coupling elongate under tension, especially when milling deep. The elongation can be as much as 1 mm, depending on the mechanical resistance and doesn't always relax, depending on depth-of-cut and material.. This problem of course doesnot happen when engraving with a laser (no mechanical resistance). Thus: a good product, depending on the application. (I am thinking about placing thin rubber sheets in the grooves and drilling the center away. But, I have not tried that yet. Installing under pre-tension does help, but limits the side-movement.)
