I purchased 2 of these.
One came apart when I first tried to fill it. I glued it and it was.fine. I used one for salt and one for pepper.
They worked pretty well.at the beginning. You can adjust the fairness at the bottom which I liked, although I would've liked it finer. It's a lot easier than a manual grinder if you're using for cooking as you only need one hand. I also liked the light at the bottom.
i wished that the chamber was bigger as I had to refill every couple of weeks, but it seems most electric grinders seem to.hold this amount.
Unfortunately the day I threw out my manual grinder one stopped working. I changed the batteries but it still didn't work.
A.month later the second one stopped working. One lasted 3 months and one lasted four.
The seller responded quickly to my email and refunded my money.
