After several grinders that failed, some of them very expensive, we came across the OXO. It gives you a nice selection of the grind you want. It's very quiet compared to the other ones that are very noisy and break easily. This grinder does a great job and is well made. But, it doesn't release the entire amount of grounds into the cup so you need to tap it slightly to get the rest out. We like how easy it is to clean and the cup is nice, easy to see in. Best grinder yet and for the money it's hard to beat. Highly recommended. Read more

I had an OXO conical burr grinder that worked great for about ten years, which is amazing for any small appliance used daily. Only complaint was that it’s a little noisy when others are sleeping. So, I thought I’d try the Aromaster because it was on sale ($79) and it had slightly better reviews. Sorry I did. Should have stuck with the OXO. Bought an OXO replacement for $88 on Amazon and it works great just like the prior one. It seems a little quieter than the prior one, too. Nothing much has changed in the design and function (if it isn’t broke…) and our coffee tastes richer, back to normal. OXO’ stainless steel container has less static than the Aromaster, too; not perfect, but much better. BTW, burr grinders are the best; don’t buy the cheaper blade grinders. The Aeromaster’s "Upgraded Anti-static Technology" worked for about 3 months and then stopped working. Now, coffee grounds fly everywhere, and we must empty the container into the brew basket over the sink. I think (not sure) they coated the plastic container with a chemical and it wore off. Our coffee hasn’t tasted as good either; not as rich, a little “plasticky”, which doesn’t make sense. Coincidence? On the plus side, it is quiet and grinds well. Read more

I love this coffee grinder! After years of using a blade grinder, this OXO Brew Conical Burr Grinder has really leveled up my coffee. The grind is so much more consistent, my pour-overs and French press have a much richer flavor. I love that I can grind fresh beans every morning with minimal effort, and it’s quiet enough that it doesn’t wake my sleeping toddler. It’s super easy to use, just pick your grind level, hit the button, and it does the rest. There are so many burr grinders on the market, researching was overwhelming. OXO is a trusted brand, so I gave this grinder a shot, and I’m so glad I did. Read more

The media could not be loaded. To be as blunt and simple as possible, the OXO BREW Conical Burr Grinder is the worst product I have ever purchased online through Amazon. Furthermore, my wife has been in contact via email with OXO's customer support team about the poor quality of this product, and their support team refuses to either refund or replace the product. We have provided them with both videos and photos showing that the unit functions either very poorly or does not function at all without lots of troubleshooting. Yet, their engineers have responded saying that the unit appears to be functioning "normally" in the videos (one of which I will attach to this review). However, at this point the unit does not work without quite a bit of frustration--plugging and unplugging multiple times or sweeping out the burrs multiple times just to grind enough beans for a pour over coffee. Even though I have only owned this unit for one month, I see no other solution than to place this unit in the trash and buy a more expensive unit from another manufacturer. I am an avid home coffee brewer, and I have owned other coffee products from Bonavita, Hario, Mr. Coffee, Cuisinart, and OXO. I can say unequivocally, this OXO burr grinder is the worst coffee product I have ever owned or purchased. I will attach video and photographic proof that the unit does not work correctly and will explain further below the problems with the unit. Initially, the unit worked great. For the first week, the unit produced a reliable and consistent grind of Trader Joe's Ethiopian beans (~$8.99 a bag). Then, the trouble started the second week when I began grinding Stumptown Hair Bender beans (~$15.99 a bag). The unit jammed mid-cycle for the first time. The button on the front of the unit would not start the motor so I tried troubleshooting the unit in multiple ways, following the instructions in the owner's manual. I unplugged it and plugged it back in--start button still did not work. I opened the bean hopper and nothing appeared jammed. So finally I opened up the burrs and swept them out. When I put the unit back together, it worked, and I thought the problem was solved. However, over the next week, the unit kept jamming every time I used it with the Stumptown beans. Sometimes it would jam multiple times in a row. Each time I had to open the unit and sweep out the burrs to get it to work. This process, while being extremely frustrating and time-consuming, also caused the unit to produce an inconsistent grind size. I've attached a picture showing that I get chunks of beans in my pour over because I have to play an elaborate game with the machine just to get it to function. For a unit that regularly retails for around $100, this is absolutely unacceptable for a new product. Furthermore, if a $100 burr grinder cannot be used on a premium product like Stumptown, then that grinder is entirely worthless to coffee enthusiasts. After I finished the bag of Stumptown coffee, I tried the grinder again on the Trader Joe's beans (since those beans had initially worked well with the unit). Now, I began experiencing the same problems with Trader Joe's. In order to grind 5 scoops of beans for one large pour over coffee, I had to either: (1) Open and sweep the burrs multiple times or (2) Plug and unplug the unit multiple times because it grinds for about 3 seconds before jamming even when the timer is set on 30 seconds. I have attached a video showing the unit functioning in this way. In the video, you will see the game I have to play just to grind beans using a unit that was purchased only 3 weeks prior. Here's my personal thought regarding the performance issues of the machine. I assume the motor has a fail-safe feature designed to stop the motor in event that it becomes clogged. This would prevent the motor from being damaged if a very small stone or an extremely hard bean got stuck in the burrs (which can happen on a rare occasion). My guess is that this setting isn't quite right in my unit and that the unit stops every time there is the tiniest bit of resistance on the motor. This would explain why I have to unplug the unit multiple times just to completely grind a cup of beans. Either way, it is entirely unreasonable for OXO to expect users to have to troubleshoot a new unit with such frequency as a part of the unit's "normal" functioning. Currently, OXO does not want to address my concerns with this unit so I have decided to place this negative review. I've never felt compelled before to write a negative review on Amazon. Hopefully, they will decide to improve the product and respond to customer concerns. At this point, I cannot recommend this product to any other buyer, and I will no longer purchase any kitchen or coffee products manufactured by OXO. Finally, I've decided I don't even want a replacement for this unit. Even if OXO offered to replace it, I would refuse. That alone shows my level of disappointment with the product. The overall build quality feels cheap to me, especially the timer and start button on the front. I owned an entry-level Mr. Coffee burr grinder (~$30) for 7 years that "felt" better--button quality, weight of product, sound of motor, etc. If OXO decides to respond to my concerns, I will only accept a full refund for the purchase price of the product so that I can purchase another unit from a different manufacturer. UPDATE: OXO finally agreed to refund us the purchase price of the unit after I posted this negative review and video on Amazon. The refund process took some time, but we did eventually get a check in the mail for the full purchase price of the unit. We will explore other options for a replacement unit. Read more
