I was looking for a water system to go under the sink , a friend at work recommended the cosmic zero. It looked a great piece of kit and customer service were very helpful and gave both myself and my freind replacement filters which was a lovely gesture. Arrived prompt with said gifts and was easy to set up. Obvious big difference in the taste of the water and the hot water settings are fantastic. On the down side for the cost I was a little disappointed in the overall quality of the machine casing and the drip tray is cheap and moves away from the connection point too easily. This maybe a little picky from myself and overall I am very happy with my purchase and I dare say the manufacturer would say the cost went in to the overall working of the machine. I would still definitely recommend to friend's and family.
