Please forgive the wordy review, but there is much to write about this product. Before proceeding, allow me to preface my remarks by stating I performed a lengthy review of customer comments & reviews across multiple sites, and I concluded this product was worth the price even though there was the potential for a couple of specific yet seemingly minor technical issues. Never before have I experienced issues with any of the four previous Keurig brewers I've owned, but I purchased this model to use at work (primarily for its small profile and purported ease-of-use). I still maintain one brewer at home and I donated one to my office, and those are still going strong. I purchased this three weeks ago and have been able to enjoy four, maybe five full cups of coffee even though I've attempted to brew a cup at least twenty times. Similar to dozens upon dozens of complaints/reviews almost exactly like mine, this is what I'm experiencing: the brewer partially drains two to three ounces of water then does absolutely nothing other than sitting idly by until powering down after about 30 seconds. Once that occurs I repeat the process of attempting to brew a cup of coffee, except I don't add more water because there already is water in the internal reservoir. Again, the brewer drains two to three ounces of water before powering down after roughly 30 seconds of 'inactivity'. (It certainly isn't heating the water!) I repeat this process until the external reservoir is empty, and eventually the brewer attempts to heat the water. However, the resulting brew is lukewarm (which I promptly discard because, let's face it, unless you're desperate for the caffeine fix you're unlikely to drink it and you probably aren't going to nuke it in a microwave - barbaric!) The most unfortunate part of this issue revolves around the loss of so many K-Cups, so I've decided this particular machine is going to be unplugged and set aside until Keurig figures out what the issue is (if anyone states it is anything other than a design flaw, they are sorely mistaken.) This brewer does not need someone like Sheldon Cooper to operate it; the operating instructions are ridiculously straightforward and easy-to-understand. Of course, Keurig customer support is likely to reply the technical issues my brewer is experiencing are very unusual, but the reviews on here and many of the 450+ critical reviews on Amazon tell a different story. Some Keurig brewers, once they have been used for a long period of time, are known to have issues with the water intake/vacuum, but there are ways to remedy that. However, that is NOT the issue with this model, as the water eventually drains into the internal reservoir. Again, while I have been able to enjoy a few cups of piping hot coffee, those are far outnumbered by numerous cups of what we might describe as a lukewarm, unflavored 'beverage'. My hope is that Keurig, a brand I've come to trust, is actively working to get this specific model up-to-par with the machines I've long used and which always have worked as expected.
