I have looked at other products over the years but can find nothing that compares with the design and overall performance of this one. The tank is large enough to dispense a pot full of filtered hot water for pasta. The cold water is also filtered, which removes the unpleasant muddy taste of our local water. I REALLY like the design--it is sleek in appearance and is easy and safe to use (you cannot run the hot water without supervision). There are few crevices for mineral buildup. Maintenance is easy.
