This is the third Keurig Supreme that I have had. The other two were replaced for the same reason. Keurig master switch would not turn on the coffer maker. The people who took my calls were extremely helpful and sent out replacements the same day
Easy, easy and easy with flexibility in selecting how you want it to brew. Only problem is if you attempt to accidentally brew without the water tank installed, you have rendered the unit permanently inoperable. It will no long turn on. Keurig could use a different thermostat with a reset function but they don't.
Versatility of coffee maker is probably it's best feature. Can make coffee at many different strengths and temperature. Have used many Keurig makers, this Supreme Plus is best on market.
