My mom and I have long wanted a mortar and he's just sore expect. He does everything, no matter what small and mixed up it super! For rapid crushing jedlicher things he's super useful and it's also super fast. It is therefore a little difficult for petite people or children not geeigent because you already requires almost 2 hands when tilting. I've never tried to mix something with oil, I would not recommend it as well Nusstückchen get stuck in the small holes and the oil probably permanently stuck indoors. but otherwise very helpful
