Excellent little grinder
For the price, this thing is a great value. I wanted to use it a bit before writing a review, because anything can be amazing initially. I have been using it for several weeks now and let me just say that for the price, you get a great little grinder. This thing isn't meant to grind up bags and bags of coffee, but for grinding a nice little bit for a few days at a time, it's perfect. It's easy to set the grind level / coarseness, and it "stays" where you put it. I have not had any issues and it seems pretty durable. I saw some complaints of it being slow, but maybe they just expected electric speeds with a manual grinder? Not sure, but for me I am able to grind a full reservoir (the container of this item) in less than a minute and a half, at best. I got this because sometimes I am lazy and didn't use the electric grinder the night before and I don't want to wake up the wife grinding my coffee, so this is PERFECT. The only thing is, now I don't use my electric grinder anymore.. The reason for that is I get more consistent ground coffee using this little guy than my electric grinder ever has. So now I am stuck in manual mode, and for cheap! This thing is super light and easy to store away, not bulky and won't get in your way. So if you are hesitant because you saw some bad reviews, just do what I did.. buy it anyway and find out for yourself. I have learned that most negative reviews on Amazon are because people expect things to be more than they are or to somehow function beyond their capabilities... This thing does what it's supposed to do, and it does it well. So buy one now, you won't regret it!

Gets it done.
At this price point it is a excellent grinder for coffee. It does adjust for different grinds but there is no scale to gauge, just clockwise or counter clockwise. Recommended if you are not sure if you want one.

It's get grinding! ;]
The coffee bean grinder is ease to use with mostly smooth consistency. It's regularly medium sized with mid noise precision. I suppose you can ideally take this puppy with you camping if you have some extra room in your cargo. All in all, it's consistently done it's job which is grinding them beansss!

Simple grinder
Great alternative to more expensive grinders, adjustable, could be a bit easier to use but the price is very fair.
