Query: works great for about 2 months

truly terrible product. Great style, but no substance. I got one and loved it, so a month later I ordered one for a friend. Mine completely died at the 2nd month, then my friend's died right on the same schedule. Thing is fussy when it does work, jams and clogs frequently. Spend your money on anything but this--amazon should stop carrying this lousy product, and I would like my money back for both of them. I think blade vs. burr grinding is not distinguishable in taste, but I just wanted a grinder with a bean hopper. This one is terrible. Makes me certain to avoid all DeLonghi products in the future, too.
