Solid all metal construction. Reliable uniform grind from pure powder to quite course. Excellent doserless design can grind into any container. Relatively low static.

The tolerance of threaded burr carrier should be better, but is easily fixed with Teflon tape as has been well documented.

There is not much to say about this that hasn't been covered. It is truly a bargain at ~$300. If you want a good burr coffee grinder, this is where you start. The cheaper ones use too much plastic to do the job reliably and will not hold up over time. You have to double the price again to get a truly bulletproof last-your-lifetime grinder. The Rocky gets 90% there. Thats my sweet spot.

I use it mostly for drip coffee and it produces a beautiful even grind. I use it sometimes for espresso and find it is perfectly suited for that having more than enough adjustment range, as has been commented on at length around the internet.

I snagged one at 10% off from Whole Latte Love just after the new year. It came double boxed it, but they kind of understuffed the outer box, and the Rancilio box and packing is a joke. Luckily there was no damage.
