Query: Really disappointing

A friend of mine owns an older model Bunn that is very good, so I bought two NHB's before Christmas; one for myself and one as a Christmas gift for my brother. Mine was truly impossible; it made good coffee, but took over 20 minutes to do so. After doing all of the recommended maintenance 3 times and trying every possible configuration, I finally just threw it in the dumpster. I notice that my brother does not use his, although I have not asked why. I really believe you would be well advised to buy this unit locally, if possible, so that it may be returned easily.
