Ask yourself why you need a battery involved in your coffee grinder. You'll loose the charger. Its barely powerful enough to grind coffee - its one and only job. This will last you 9 months and you'll need to replace it

[This review was collected as part of a promotion.] Recent made our first batch of coffee using this grinder. It was quiet, thorough, and all around very nice. My spouse was concerned that there weren’t pre-set buttons for different types of grinds, but she’s certainly happy with it now. It’s far better to gauge ‘course’ or ‘fine’ with your eye. My cup of Gesha coffee was about the best I’ve ever had.

[This review was collected as part of a promotion.] Great product and grinds extremely fast. My ONLY criticism would be that if you want it VERY fine by the time it gets close to the desired consistency, it starts to clump up under the blades requiring a spoon to detach from the container. Problem with this is, now the grind is compromised as you have clumped coffee which you then need to break down manually. Other than that, it’s a very convenient machine and happy with the purchase!

[This review was collected as part of a promotion.] I was amazed at the power these appliances have. It is so convenient to not have cords getting in the way. I also bought a second one to use for grinding spices. I pretty much have all of these now except the vacuum.
