The Encore ESP has been working great, you do need to make sure it's the ESP though as it can grind finer than the standard Encore. It has some retention issues that I'm sure a more expensive grinder might solve but otherwise I have no complaints at all, I never need to go anywhere near it's finest grind size.
I ended up buying a third-party single dose funnel and bellows that I would recommend, helps push out the grinds that get stuck and makes the grinder overall a lot smaller
