Query: Many flaws

I've owned a Bunn ThermoFresh Brewer for over a year. Don't bother purchasing this item. The carafe has a design flaw that causes coffee to spill onto the counter every time it is used. Bunn customer service says that it's a possible build up of oils from the ground coffee that is causing the leaky carafe. Their fix is a cleaning with warm water and soap. I've cleaned it numerous times but that is not the problem. The problem is pour design of the pouring spout. I thought Bunn was a quality item. Boy was I wrong. I will never purchase a Bunn product again. There are other issues with this item but not enough space here to elaborate. Do yourself a favor pass on Bunn.
