I used it for about a year and half for espresso and had to replace the adjustment ring 2-3 times in that span. Once I broke it because I tried to grind Ritual's espresso blend fine enough for espresso. After that it was simply espresso blends in the range of Redbird, if you buy a Preciso expect to be fixing it at some point, YMMV, but I doubt you are going to be using for more than two years without having to at least switch out an adjustment ring or two. If you're fine with that compromise it's a great a grinder for the money.
