Some consumers that own Keurig's really love them. It's almost an obsession. I have one in my house and don't really get it. I don't like that it heats up a plastic cup to coffee hotness level. I feel like the coffee it brews is fairly weak. I tried using it with reusable cups to grind my own coffee but then it's even weaker.

However, those that like them, really like them. There are iced beverages you can make with them, or even hot apple cider. I guess this is niche, but those that will use it will get hooked.
