Bests & Worsts Reviews from Amazon

I've had three Keurigs over the years. This one is better than the other two (both were the original, I don't know the model number), in that it's quieter. Noticeable quieter. Brewing is about the same (which I like). BUT, about 20% of the time, this doesn't work at all. The pump (I guess) makes noise and either doesn't do anything or brews a few drops only. The problem didn't start until after a few months, but I wish I still had my old one. Truth is, I'd seen other reviewers saying the same thing, but I hoped for the best - wish I'd listened. Not happy.
