The unit makes a nice and solid impression. Practically, the flexible USB connection, which makes the placement very pleasant. Once the device is recognized by the notebook, it works quite well. Unfortunately, this is also the crux of the matter. Often it is in fact not recognized and one must often push certain buttons until it works or not. Probably blame is the dual function as a numeric keypad and a calculator.
I would not recommend the product rather, because it is ultimately very annoying, to put it in motion.
