Query: Multiple Problems with this machine

The first thing I noticed about this machine is that it grinds way too much coffee per cup - nearly twice the standard amount of 15cc (1Tbl)/cup (it ground nearly 30cc or 2Tbl/cup). You can get around this flaw by just setting the grinder to half the number of cups that you want, although that becomes challenging when you want to grind small amounts (< 4 cups). The second problem is that it often jams - probably 20-25% of the time. When this happens, the amounts are all thrown off. The third issue I encountered is that this unit just plain died when it was less than 6 months old. As far as I am concerned it was a waste of money.
