The K15 is the first coffee maker that uses pods and I have to say I'm pretty happy with this one. The machine is extremely easy to use and it works really quickly. So far I've tried it for both coffee and tea pods, but you can even buy soup pods (which is pretty cool) as well as a reusable filter so you don't need to waste plastic and can choose whatever coffee brand you want (I'm guessing it would probably work with tea leaves too). My only complaint is that there are only three drink sizes and the smaller one (6 oz.) is still a little too large for my taste when making coffee, since I kinda like my coffee on the stronger side. It does however simplify the tea-making process immensely and you don't have to worry about leaving the leaves in for too little or too long.
