Really enjoy using this machine. The unit is very simple to use and makes some really nice coffee. The included extra fresh grounds basket allows you to custom blend your own favorite coffee to exactly the way you choose. Of course remember you can use any of the K  cup type of coffees. No The machine is well made  and nice looking on the counter.  Only wish for a few minor changes. The overflow container is to shallow to contain much of a overflow and It would also be nice if the brewing sequence was a little faster. Please read your instructions. You will find that if you use your cup or mug that you are using, filled with the proper amount of water then poured into the reservoir and brewed you will not have any overflow. The machine is designed to brew the full amount of water ( up to 14 oz. ) that you add. All parts are easily removed for cleaning. The Flex-Brew is a joy to use and I enjoy it's many advantages and some really good coffee.
