I miss my Braun KM-30. I bought it in 1999 for $35 at an appliance store that specializes in factory reconditioned small appliances. So, it was factory reconditioned then, and it worked right up to the present day. However, I was never very diligent about cleaning it, and years of rancid coffee dust had accumulated to the point that, once it was cleaned, it just smelled horrible. I bleached and oxy-ed the hopper and removable parts, but it still managed to impart that horrid smell and taste to my coffee. So I bade farewell to my good friend.
In seven years of hard use (three pots of coffee a day) it never once gave me any trouble. My mother has the same model, and she's been using it for about ten years. It always ground consistent uniform granules. I never tried grinding ultra-fine espresso with it, so I cannot speak to its abilities there. I used it for auto-drip, my Krups moka brew, and press pot. And it did great for that.
This grinder has a resevoir for the grinds that attaches to the base of the grinder, butting it up against the housing of the grinder. This is where it was messy; removing the resevoir always resulted in fine grinds flying out onto the kitchen counter. And this grinder was the noisiest thing I ever owned, and I own a Harley. My wife used to throw a kitchen towel over it when grinding coffee. And if someone was on the phone, they would have to go upstairs so they could hear their conversation. The big complaint I have about this machine is that it is not very easy to clean. The hopper detaches from the adjustable base, and the base unscrews. But, there are a lot of crevices and crannies for coffee dust to hide, and cleaning is such a chore that it is easy for one to simply not do it properly.
All in all, this grinder had a helluva run. I bought it reconditioned over seven years ago, and got great coffee out of it. Had I been more aggressive in keeping it clean I would be using it today. However, due to its relative scarcity in my area (and the noise and cleaning) I opted for the Krups GVX1 to replace it. But, had it been readily available I likely would have bought another one (I don't buy appliances online-hands on kind of guy).
