Must be taken apart and cleaned after every use according to instructions. That alone makes it inconvenient.

Next to impossible to turn crank on hard winter wheat grains in order to get the flour fine enough to not crack your teeth on. Unless you plan to make large grain wheat "mush" cereal, get an electric mill. This doesnt work for milling baking flours.

We just got one and it is a terrific old design like Grandmother had. Great for anything from coffee and spices to making flour.
But there is some confusion over marketing names and model number. Various retailers have offered it or still do as the Porkert 150 made in Czech Republic. But there is reorganization in US distribution, and there seems to be attempts to take advantage of the confusion with price hikes. Recently it has appeared under other names and model numbers - some are shoddy copies with poor castings and worse tinning made in S. America. Others, still made by Porkert, but carrying other brand names. Shoppers should be wary about buying the genuine Czech model, but also about paying too much in the confusion over distribution. This model is available anywhere between $69 to $120 for the real thing. But only $22 - $50 for the knock-off. Another thing to check: are the included burr wheels steel, stone, or does it come with both kinds included? (You cannot grind wet chick peas with stone burrs as they gum up.) Does the seller provide the other wheels. Some don't.
