These stink should have just got the battery operated ones. The charging dock is very finicky to lay the grinders in. The grind quality control to make it fine or course is very loose and does not really change the difference of what you get out of it in terms of size of the grind. The biggest complaint I have is the covers on the bottom, make it hard to use one-handed I don't want a puzzle or another task to do when I go for salt and pepper. It's very tedious and a minor detail, but something to think about that, you have to open the covers on the bottom and close them every time you use it I have found a workaround where some folk have been able to unscrew the bottom cover and just remove it completely however, I have found that when I do this, they do not sit properly on the charging dock and if they weren't already finicky and delicate to get on the proprietary charging dock doing this makes it way more difficult.
