First, let me say I am very happy with this 2 pack set of grinders. Here are some things to know, some good, some maybe not so good depending on your take of things. First the good. These things crank out salt and pepper like a champ. If you didn’t notice, the battery is way above most grinders (800 MAH). They keep on crankin like the energizer bunny. I haven’t had to recharge them yet so I don’t know how long they will last but the salt and pepper are almost gone and I filled them to the top. Oh yeah, about that, they hold a good bit more than other grinders as well.The adjustment on the bottom of the grinders is easy to adjust and you can adjust these things down to where they put out dust or all the way up to those giant flakes the fancy restaurants put on your steak.Out of the box they were about half charged and it took only an hour or so to get them fully charged but what I wanted to tell you is the charging port is in the TOP of the grinder. Which is where it should be. I’ve seen other grinders with the charging port at the bottom. Thats pretty dumb as many people reviewing those grinders had constant problems with corrosion and the ports not working anymore. You won’t have that problem with these and by the way each grinder comes with its own USB C cord. No charger. Really though you don’t have one of those layin around in a drawer somewhere?On the bottom of these grinders is a dust cup. That might not matter to you but it serves 2 important purposes to me. First it keeps your countertop clean. And second when you need a teaspoon of salt, pepper, or whatever spice you put in it, you only need to start grinding away with the dust cap still on. Remove the dust cap and voila’!The last great thing about these grinders is that on the bottom of each grinder is 2 bright white LED lights. And man they are great. My old tired eyes can see exactly how much spice I am adding to my food.And now the bad. These grinders are in a transition phase with the manufacturer. We loved them so much we bought another single grinder for a smoked salt we use. The unit looked identical to the first two we bought but there was only one small warm white (yellow really) light on the bottom. A BIG difference in how easy it is to see.There were other small insignificant differences with no effect on usability. Same battery, motor, storage capacity for spices, etc. When we contacted the manufacturer they said that it will be that way until all the old units are sold out. They made the change due to customers wanting a brighter light on the bottom. I think it’s only fair that people know this, however…………..if you read the description, it clearly states that it is one warm white light and they even show it in the picture.I believe that far fewer people order the single unit instead of the two pack and that is probably why we got an older unit second time around.Regardless of which one you get this is a good purchase!
