I purchased this set of gravity grinders for my sea salt and pepper by #Meelio as I have arthritic hands and figured t h.g esecwpuld be so much easier to use. I was right. It uses 6 AAA batteries but I like that you just tilt it to 90 degrees to activate it and that you can adjust how coarse the salt and pepper come out. I also love the led lights on the end. You get a set of 2 of these amazing grinders for $27.99. This is a fair price and one I wouldn't mind paying for such quality and that allows me the ability to grind my salt and pepper the way I want without asking for assistance due to my arthritis in my hands. I highly recommend this product.
