Keurig® OfficePRO K155 Premier Brewing System

I've had this exact same model for going on 10 years now. Other than cleaning it I have had absolutely no maintenance involved with this maker. I don't want to even have an idea how many hundreds if not thousands of gallons of water has gone through this coffee maker hundreds if not thousands of gallons of water has gone through this coffee maker and it works seamlessly. I hopped on here just to see what other offerings were available and cannot believe this is still available for purchase. It is the gold standard in Keurig coffee makers.

This machine was gifted to me years ago (it was used when I received it) We have been so happy with it. It finally reached its end of life today. I turned it on, went to refill the tank, and hot water started to pour out of the hole on the base of the machine. I'm planning on getting another one. What I like about this model: 1- the tank size is large enough that we don't have to refill it constantly. 2- the two drain hoses in the back allow me to clean it better and allow lime scale to drain out. 3- the touchscreen is so simple to use that your Granny and guests can figure it out on their own - without an instruction manual. 4- I also like the water tank being on the machine instead of on the back. I have used a lot of other types of keurigs that family and friends have had and this one is my favorite. I do have to say that cleaning the machine regularly is important. Not just for the timescale, but for black slime/mold that I have drained out of it. That is super gross but I believe every machine that has hoses and a tank probably have this and we just can't see it. But if that could be fixed would be really good. Overall, I have always thought this was the best design for these type of keurig coffee makers.
