I bought this a couple of years ago because I didn't have a grinder at home. After purchasing it I realized that it was not the best grinder for my needs. It does look nice, and has better results than a blade grinder, but what doesn't? It might be good to have if you don't mind a muddy french press or require the perfect cup every time. For $50 it's not too bad, but only because a decent burr grinder can be almost three times as much.
I would recommend doing a little more research before going for this grinder. It was a decent starter, but the cons outweigh the pros. I have since spent money to upgrade, and it was well worth it. The results that you'll get from this grinder may not justify the total money spent when looking for your ideal grinder.
