I've owned maybe 4 different traditional grinders over the past decade or so, and they've all been quite decent, though somewhat tedious to use. You gotta break down buds to make them fit and can't put too much at a time, the teeth are a pain to clean, and the construction quality was never perfect.
The premium stainless Flower Mill, however, is awesome. For first impressions: The build quality feels *very* solid, the precision is impressive. The quarter-turn lower catch is very smooth and convenient. The magnetic lid is both neat and convenient. Overall presentation is quite nice.
As for usage, it's again awesome. Both the milling chamber and lower catch are quite deep, and the removable screen even gives you a little extra room if you're like me and don't have much use for separate kief. I don't have to break down or even touch the buds anymore. Just pour a couple into the chamber, put the lid on top, and grind.
And the grind is *so* easy and smooth, like ridiculously so. With traditional grinders, sometimes it felt like the flower would just never fully grind - getting stuck between the teeth or just being really tough to work through. But with the Flower Mill, it's seriously so easy and quick. It hardly even feels like it's grinding anything. Just apply a little pressure and turn back and forth, and after 5-10 seconds you've got perfectly ground flower.
Cleaning is also made easier than most grinders. Pretty much every piece of the mill comes apart thanks to some clever construction, and since the milling plate is just a flat disc rather than a bunch of teeth, it's way easier to clean.
I only have 2 minor complaints: The 2" – while very spacious, probably more so than my last 2.5" traditional grinder – is still a bit small to hold. It just feels a little awkward, and makes opening the lower catch require a little precision in how you hold it. I will likely upgrade to the 2.5" once they're back in stock.
My other issue is that I can't unscrew the rotor knob (the top piece of the milling chamber). Flower Mill provides a really handy video on how to clean your mill, which shows them unscrewing the rotor knob by hand, but I was completely unable to do this. I even resorted to trying to use pliers, but that still failed, and despite using a little padding I still wound up accidentally scraping the bottom outer lip of the lid. That part is my fault of course, but nonetheless due to how tightly screwed on the rotor knob.
However, that's it. Those are my only complaints. I never thought I was going to be wowed by a grinder/mill, but this is easily the best I've ever owned, and I will happily recommend this to everyone!
