They are a little smaller than I expected but they are solidly built and work well. They have a nice heft to them and I like the thumb-trigger action (as opposed to the more traditional twist action). There is no mechanism that allows you to adjust the size of the grind but that doesn't bother me at all. The product listing says it comes with an acrylic base to hold the two grinders but I did not receive one. That was somewhat disappointing but I'm still very happy with the quality of these grinders.
