Update: May 2017. See the comment posted below. I was unaware that the mills would disassemble from the base. If I had known this, I would have gladly given the product 5 stars, so I've changed the rating. I've left the original review below because I do believe, given enough time and use, the mills would need to be taken apart to be cleaned. Use care with the threaded view windows. Other than that, these are good, solid grinder mills. I've been using mine for more than half a year now with no issues. Highly recommended! And a special thanks to the company for posting their comments.A handsome and impressive pair. The stainless steel finish looks good and is easy to clean. With grinders this small, there are always sacrifices. For starters, they're not adjustable, but what comes out is neither too coarse or too fine. And the salt mill seems to drop a little more than the pepper mill. My biggest concern is longevity. The way to refill these is to unscrew the bottom half from the clear acrylic center. Not a problem in or of itself, but if the threads on the acrylic part ever get 'boogered up' or stripped, these mills will be useless. I would advise anyone who has these to exercise EXTREME care when refilling and re-attaching the base.To me, this is a set to put aside for special occasions...those intimate dinners for two, to 'wow' your friends or guests, or to keep on the bar for making those spicy Bloody Mary drinks. But for everyday use? No, I'll still fall back on traditional shakers. That's not to say I believe these mills are fragile, but I don't see them practical for everyday use or for cooks who depend on precise measurements.
