“It works really well, and I can even make coffee with it — that means it also works as a coffee maker. It can be used in many different ways. It’s a very good product — excellent!”

This mini grinder is okay for light work, but definitely not suitable for professional use. The bits work fine on soft wood and take a lot of time on stone, but they don’t perform well on metal. The cutter discs included are of very cheap quality and break easily, which is disappointing. Also, the heavier the work, the faster the battery drains. And it heats up fast too, Overall, it’s only useful for small hobby projects, not for heavy or professional tasks.
