At first, I would have definitely given this pepper grinder 5 stars. It was nice to have an electric pepper grinder that is easy to utilize with one hand while cooking. I liked how you could chose the fineness of the ground pepper that comes out....That being said, filling it is rather awkward and messy. You must take out the battery pack to add the peppercorns, and once it is screwed back into place, it turns on and grinds until flipped over. After one refill, the battery pack "handle" itself broke, so that it would not pull out easily. We were able to "fix" it, but every time we had to refill it, it would break again. Then the 3rd time we refilled it, the battery pack got stuck, and since the handle was broken off of it, I couldn't get it out. I tapped it lightly on the counter and the whole thing just fell apart!
