I cook a lot, and having the electric salt and pepper grinders is such a time saver! I make a lot of meat including steaks, and I use lots of salt and pepper. I love how these have a large reservoir so they do not need to be refilled very often. You can also adjust the grain size of the salt and pepper to your desire, and its fun that there is a blue light that comes on automatically when you turn the shaker over to use. I also love that they are always 'ready to go" and you do not have to do anything but turn them over to use them! I had a few other brands in the past, and they always stopped working shortly after purchase, but I have had these for a while now, and they are holding up well!
