Query: Not really worth it

It worked well the first few times I used it. However after two weeks of use it has basically fell apart. The filter is not of great quality, or perhaps the high pressure from the hot water jet was too much for it to handle. On a positive note, it was awesome to be able to brew my own personal blends of coffee from caribou, Starbucks, etc. Good concept, just wish it was more sturdy. And it wasn't exactly cheap either.
