UPDATED Nov 2021:After 6 months mostly daily use, the grind slowed down. Progressively slower, until at the 9 month mark it was waaaay slow, like 45+ seconds for what was 15 seconds before. And less effective at producing varying fineness of grind.Presumably it was clogged (or the burrs wore out dramatically fast), but my repeated, progressively more aggressive attempts to clean it out didn't help. Finally reached out to Oxo who after checking that I had done a full cleaning, sent me a replacement unit (apparently new, not refurb). Advanced shipment with a prepaid label for returning the bad unit. Nice.I'm not dropping my rating because of the quick advance-exchange warranty service, but the issue did verify my early concerns about the unit's design with the fixed bottom burr and no access to the chamber beneath. If this happens again within a few months, I'll update my review again and change my rating.Note the unit has a 2-year warranty.(orig review follows)----A decent conical burr grinder system.It has a very consistent grind, is reasonably quiet & is easy to use. On the negative, it's a little annoying to clean, with a quirky "timer" based on/off. More details, and comparison to Baratza below.After 6 weeks of daily use, I'm pleased (especially for the price) and I'm "keeping" it. I can literally taste the more nuanced flavors from the more consistent grind, using the same beans & serving sizes. I'm happy.Good:* Quiet for a grinder. Doesn't even make my cats' ears twitch.* VERY consistent grind at all settings I used, from (barely) fine to (moderately) coarse. This covers most of the grinds I use at home.* Faster than the low-end Baratza.* Grounds bin is stainless, minimizes static cling.* Top bin seals tightly, in case you store more than a day's worth of beans in it.* Easy set up.* Top bin has a nice locking mechanism.* For oily/dark beans, it doesn't seem to catch any grinds inside the mechanism.* Top bin & top burr both very easy to remove for cleaning.Odd / bad:* Bottom burr does NOT come out.* Inside of mechanism is sealed, and the grounds path isn't straight, making thorough cleaning a struggle.* Timer backs up an instant-on button, rather than a normal on-off toggle.* Non-oily / medium-roast beans seem to get caught in the mechanism (as much as a full tablespoon+ of grounds) and the vendor solution of "run it empty for 10 seconds" doesn't help. You have to stop / start it a few times and a teaspoon of grounds falls out each time. The machine works MUCH better with the oilier dark-roast I normally use.Thoughts on the timer: I'm a bit confused by other reviewers being used to this. Do they go to the gas station & ask for "3 minutes of gas"? I guess if you tend to walk away from your grinder, don't want to wait for a few seconds, it provides a failsafe shutoff?But I'd rather just have an on-off toggle like other brands. As it is, I set the timer to 20s and use the instant on-off button normally. Timer dial & instant on-off button pictured.Thoughts on cleaning: With the dry beans, they seem to catch inside the mechanism. You have to start/stop the device a few times (a single 10s run like OXO suggests doesn't do the trick) and some more grounds come out each time. Nobody using a burr grinder wants stale grounds...It would have been VERY helpful if the bottom burr came out. Or if the front of the device opened enough to allow it be brushed out. You can't brush it out from the bottom (I tried with 2 kinds of brushes), the inside path is too curved.You're left with two options:1) run a small amount of uncooked rice through the unit, which will capture oils and push along any trapped grounds. But it's an extra step and may wear down the burrs.2) Or you can turn the unit upside down, and try to shake/tap out the unit, but this may also be bad for the mechanism's longevity. And it's a pain...I came from an old KitchenAid flat burr grinder, and this conical system is more consistent, much better at feeding itself without needing beans pushed down, and is MUCH quieter.I also tried the entry-level Baratza, which has a similar design. That one is about half again more expensive, with a more traditional on-off switch & more solid build. But is slightly louder, a bit slower, with a delicate silicone gasket that has to be removed for every cleaning. The Baratza is slower-- which might be a goal for burr purists, but may be an annoyance for the morning coffe-hound.Considering the price difference, the OXO is (so far) slightly superior for my criteria.At this price under the century mark, the OXO is an outstanding grinder. it's reasonably small and aesthetic, and works well. Quirks aside, if you use the same kind of beans I do, the cleaning issue seems addressable. Although the design may limit the unit's lifespan, since you can't replace the bottom burr and have to run it empty or on rice more often.It could have been perfect, but as is I'm still happy to call it Recommended.
