Bought my MM about 6 or 8 months ago, it's a pretty good grinder, I cant see myself upgrading any time in the future, if ever.
Now the point has been made "and rightly so" elsewhere, that the dosing mechanism has a tendency to throw to the left, I can imagine in a busy cafe, this characteristic would drive you crazy but I find in a domestic situation it's a non issue, simply slow your dose rate down a little and the grounds will drop vertically into the basket, however if you belong to the machine gun dosing brigade be prepared to modify the doser in some way or sloooow down a little. 😉
