Owner's manual

Q: bulk coffee

Q: I have been trying to find the water filter for over an hour! Here is a pic of my machine, does it even have a filter and do I need one???. My machine says Keurig 2.0 on the lid

A: undefined

Q: Does the k400 need the water filter?

A: No, this product does not require a filter.

Great Coffee Maker!
Bought this for my mother as a christmas present for my mother, and we absolutely love it. Not a thing wrong with it whatsoever. We both love it because it makes cups super quick and includes the Carafe with it with some sample k-cups.

I love my new Keurig 450 Brewing System
I have to be honest, I'm not sure what to say about the star rating on this. Taken by itself, the 2.0 series is a nice, if not strictly necessary, upgrade. The four-cup carafe capability is an interesting addition, although I'm inclined to think that it's a waste of effort if Keurig never bothers to bring out a My K-Carafe attachment. According to Keurig's website, it also supports Vue cups, which is mainly of use to people who bought into the Vue system. (If you did, I have no idea what you were thinking. Here's your way out.) Coffee is hot and appropriately tasty, and (hallelujah) the system is self-priming, which means no poking at the thing six or seven times when you haven't used it in a month. But that lockout thing... that's a doozie. The workaround is easy enough -- slice the foil off the top of a licensed K-Cup and put it on top of whatever you're putting in there, making sure the sensor can see the label band around the edge -- but it's the principle of the thing. Keurig, in trying to escape the inevitability of losing business because of an expired patent, has attempted to remove the one thing about its system that set it apart from other single-serve coffee systems, the ability to opt out of the Keurig ecosystem. Even the My K-Cup no longer works; even with the workaround, it won't fit properly in the chamber. (The Melitta semi-disposable pods I reviewed a year or so ago, though, work well enough with the workaround, as I assume will most smaller K-Cup replacements.) When you get right down to it, Keurig misfired pretty badly on this one. The coffee maker itself works pretty well, and if you don't mind tinkering, you're good to go. However, if you prefer to have things work out of the box, or if you just avoid DRMed things as much as possible on principle, the 2.0 series in general hasn't much to offer you. UPDATE: Yes, it supports Vue cups just fine. It doesn't explain how to use them in the manual, although the Vue cup boxes say to use setting 4 on the touchscreen.

Love the size combinations and ease of use.
After having a B60 for awhile, it gave out. after comparing this from the k300, and k500 I determined for the cost (sale price at the time) this was the best for the money. It has a color touch screen that is extremely easy to use and set up was quick. It is like any other keurig machine except you can now do a 4 cup pot. Coffee comes out as expected and hot.
