Thanks to Mr. Coffee I found exactly the kind of coffee grinder that I need: Easy to use and cheap.
I found this particular coffee grinder model (IDS77) at my local Walmart for $19.95 about a month ago. By now I’ve used it a few dozen times and have not encountered an issue thus far.
As a safety feature, the “On” button at the top of the devise will only work when the whole thing is assembled and the top is securely closed. Then the blades throw the coffee beans around during the grinding process so that they are ground evenly.
To make sure that all the beans are ground evenly, you can shift the top part of the unit around to scrap off any of the finder grounds that may have adhered to the side. As you can see in the photo above, there are little plastic liners that scrap the inside of the transparent coffee ground compartment.
This Mr. Coffee grinder easy to disassemble and wash, because all the parts that touch the coffee beans can be detached from the motor unit and placed in the dishwasher. Also, the way the detachable unit is designed makes it almost impossible to cut yourself on the blades.
A trick I discovered: Although there is a “max fill” line, you can cheat and fill the grinder past this line as long as, while you are grinding the beans, you shake it in a circular motion to make sure the lesser-ground beans cycle to the bottom. This way I can grind two days worth of beans at a time, allowing for about 30 seconds of additional sleep in time the next day.
