I have the Keurig B60 Special Edition Brewing System. The first 2 that I acquired had to be exchanged because the filtering system stopped working after about 2.5 months of use. But now that I am on my 3rd one (no additional cost to me as each exchange as a result of exercising their warranty), I have it for over 3 years with (knock on wood) absolutely no issues. It is convenient and quick and allows for 3 sizes - although the small is really mini and the large is really just a regular. The Kcup coffee options are endless and I love trying different flavours.This sigle serve coffee system is quick, easy, and convenient. A fresh cup of coffee only takes a minute now which is also a huge time saver. And I no longer feel guilty about having to throw out a whole pot of coffee for the sake of drinking only 1 cup per day.
