Unless you handle high volume grinding, get the doserless. It's much easier to use and produces great results.
Positive Product Points
Provides consistent grinds. Easy to dial in for espresso or drip coffee.
Negative Product Points
Some coffee remains in chute. I've learned to give it a couple of shakes when I'm done, which keeps the messy grounds under control. It's awkward to switch from regular coffee to decaf, since I have to tip it upside down to empty beans out. I've ground a little decaf and put it in a sealed container to reduce the inconvenience. I know that isn't the best recommendation for freshness.
I ordered this in conjunction with Rocky Silvia espresso maker. It is very good for espresso, and has also made it much easier for our basic drip coffee maker (Krups Thermal). A big improvement over the mill grinder I was using before. I love being able to grind only the exact amount we need, and the ease of dialing the right grind for different coffee makers.
I originally ordered it with the doser, but quickly realized that was a big mistake. It is probably good for high volume use. But we only brew one or two espressos at a time, and the doser was a huge pain. I found that I had to grind a lot more than I could use immediately just so the doser basket would have enough to dispense even amounts. Even then, it tended to be inconsistent. Then the leftover coffee sat there getting stale. It also made it very inconvenient to switch between espresso and drip grinds. This is a heavy machine, and turning it upside down while shaking coffee out was difficult and very messy. So, within a week I returned it for the doserless, which I love. It's much, much easier to use and is very easy to switch between espresso and drip grinds.
Aabree Coffee was helpful and prompt with deliveries. They handled the exchance from doser to doserless without any trouble. (I suspect they might be used to it.)
