Super happy with this purchase. With the press of a button I have freshly ground salt and pepper...makes a big difference in taste. I appreciate the lighted bottoms which make it easier to see the quantity being dispensed. The charge has lasted a full month so far with near daily use. They are attractive on my counter and the tray they sit in collects the loosened remnants and is very easy to clean. May give as gifts this year!

Poor Grind Mechanisms

Color: Upgrade Black, Size: Rechargeable

Salt grinder fell apart in 6 weeks. The item looks nice, but the grind settings on both the salt and pepper did not yield truly different grind. They always came out the same size, regardless of setting. About 5 weeks in, the clear plastic bottom came off of the salt grinder. I wasn't even using rock salt, just coarse salt. I could not get the piece back in. Then, the entire grind assembly came out as I was cooking. This item did not even get daily use. I purchased a different brand several years ago, I wish I had purchased that one again. I thought I was getting a good deal based on reviews. **UPDATED 9/19** Seller made reasonable accommodations to make it right. Very pleased with how this was handled. Stars reflect customer service,

very well made and super easy to fill and clean. great price and the dial for coarseness is great. i have arthritis and can no longer do the twist version of cracked pepper and salt. This makes it so much easier to use. The light is a nice feature.
