Started leaking on the second brew.  By the fourth brew I could not get the mechanism for the dispenser off without using pliers due to it had started to cross thread because it is only made of plastic and is not designed to be removed frequently, despite needing to do this after every second brew.  I ended up destroying the rubber tube (it would not pull off the bottom drain) because of having to use pliers to get the mechanism apart.  Seems that there are no spare parts to purchase so this is a very expensive piece of garbage.  So much for saving money on fancy cold coffee drinks.
