Consumer Reports

CR’s take: The Bodum Bistro Electric Burr Coffee Grinder does well in all our grind tests, but it stands out for its coarse-grind performance, where it receives an Excellent rating. This model is easy to clean but not as convenient to use as other top-performing models, due to unclear markings on its controls. The Bodum is also one of the two noisiest grinders in our tests—we're talking about as loud as a vacuum cleaner. But because you use your coffee grinder only for a minute or two at a time, the noise is more of a nuisance than anything else. This model features 12 grind settings, an auto-stop feature, and a timer.

Are you seeking to make the best cup of coffee affordably? If so, then the Bodum Bistro will be a perfect building block for your morning coffee setup. Although we wouldn't exactly call it cheap, it rivals the grind consistency of our top scorers and costs much less. That means you get nearly as high-quality grounds with a much smaller hit to your bank account. 
The most significant sacrifices you make with the budget-friendly Bistro are things that are peripheral to the quality and consistency of the grind itself. For example, this machine is a bit louder than some of its pricier competitors, has a higher tendency to spill fine grounds, and comes with fewer programmable features. However, none of these slight downsides ruined our morning coffee experience. These modest drawbacks will likely be well worth the cost savings to the majority of coffee drinkers.
