That looks like a clone of the Martek which I've owned for many years. The Martek is 'OK', works best on drills from about 4mm upwards and drills that are not too bad before you try sharpen them. There's a learning curve to go up with it. Below 4mm the sloppy tolerances make it harder to get a good result and you can end up with deep groves in the stone. Generally does a fair job on a 6mm drill.
