Bests & Worsts Reviews from Amazon

These machines are prone to not pumping water and "short-cupping" (delivering too little water into the cup). Keurig likes to tell people they need to descale because that means its a user problem and not a design problem. But using distilled water won't prevent the problem. If it did, a lot of us would be happier--not thrilled but happier. You need to read through all the comments to understand the prob. Keurig has changed the pumps in their design (or changed their pump source and materials) at last 3 times in the last two years but the problem isn't the pumps either; it's the valves. The most reliable way to unstick the valves is to remove the water tank, unplug the device, hold it upside down over the sink and give it a good whack on the bottom. Really, this works. If you think that's an ok way to operate a device that costs this much, then this machine is for you. More recently we've heard that Keurig support is telling folks that they cannot get a refund or replacement under warranty anymore because too many machines have been returned. Not honoring warranty? I don't see how that's legal. I can believe they are overwhelmed with returns, but that's the cost of business when you sell a bad design, keep selling it, keep insisting it's just scale build-up, keep refusing to support customers and continue selling the product. I believe they should have had full recall or refund for its customers. I know it sounds like I'm just another ranting reviewer but it really is a awful situation.
