This is a great little machine. It is small enough to fit on limited counter space, which is important when you live in a studio in the city. The water is single use, which isn't ideal, but that is what you get with a smaller machine. The water heats up within a minute and it works great! You can use regular size cups with this machine. A tallish mug works fine! My only wish was a 12 oz. max rather than 10. I like larger drinks, especially when it comes to teas. All in all, I would buy this product if I had the income to and if convenience was an important factor to me.
