Great Salt and Pepper Grinders, only issue is one of the jars, doesn't sit flat.I would love it if the company would contact me and send me a new flat Jar to replace the crooked/non-flat Jar.Otherwise, this is a great set of Salt and Pepper Grinders. Nice lite, charge easy and fast. Easy adjustments and provides a wonderful grind.I love these shakers! I did have problems with one and reached out to company because I couldn’t return to Amazon, they were quick to answer me and after sending a video of what shaker was doing, they are sending me a new one! Great customer service!Salt and pepper are brought to a new and exciting level by charging with high voltage. It's a delight to watch your dinner guests tongues literally smoke and catch fire. Granny got such a jolt that her false teeth flew across the table and bit uncle Billy Bob in the nose. Certainly will liven up your dinner party!UPDATE: Sorry I was confused and delirious at the time when I wrote this review. I'll correct and clarify: it was my cousin Bernice Clump who got bit on the nose. SORRY FOR THE CONFUSED MISINFORMATION!My wife experiences pain when using her hands. Not having to twist a grinder makes her life a little easier. She absolutely loves these electric grinders and uses them daily.I've owned this for quite some time and feel I can give this a good review now. Looked all over for a nice matching set thats USB rechargable and in the black and white color option. For the price this can't be beat. I had battery operated versions that ate through batteries. I looked at other options but they were just way too pricey for a salt and pepper shaker IMO. This looks very nice, and is very easy to use. Wish it had USB C but that would most likely made it more expensive. The on off button is redundant as you cant tell if its on or off unless you turn it over. Slightly loud but that's also expected at this price. Overall a great buy for myself as the volume isn't a deal breaker for myself.Pros:- Matching Set- Looks good- Glass container ( can see when you are low )- Price- USB Rechargable- Great battery life- Works with Gravity ( turning it upside down )- Comes with charging cordCons:- Rubber power button ( can't tell if its on or off )- No USB C- Loud when in useThey charge up easily! They are easy to fill and adjust coarseness. It takes a couple times to get used to turning over to start. The button is nice. Only negative is there is no cover to close the grinders when not using., but that’s ok!Gifted these to my husband and he loves them. They are a nice addition to the kitchen counter. They are not very noisy for a grinder, but are effective. There are coarse options from very coarse to fine powder. The light seems like it isn’t necessary, but I have rather enjoyed it.Very easy to fill. No batteries needed.
