I have been using a Phil mill for well over 10 years. Initially as a convenience for extract/specialty/partial mash brews, but about 6 years ago I switched to 10 gallon all grain.
Get the drill attachment, the hand crank is too cumbersome. I use a variable speed hand drill which works well.
Crush is consistent. Other mills may leave a more intact husk, but I don't condition my malt and I have no efficiency, clarity or stuck mash issues.
Durability: after probably 1000 pounds of grain, it is starting to show some age. The bearings are a little looser. Still works fine, but I doubt it will go another 1000 without at least a reconditioning. The roller itself shows no wear, just the bearing.
Feeder: I drilled out the feeder hole to fit the wide mouth generic 3 liter soda bottles so it feeds more uniformly then the smaller opening designed for normal 2 liter bottles. This was adequate for small amounts (about 2 pounds? ) of grain, but when I went all grain, I just rest a massive funnel over the soda bottle to make a hopper that takes about 10 pounds at a time. It works...
I hope this is helpful for you.
