        I purchased this based on the system capabilities and design. I specifically liked the fact it reintroduces desired minerals back into the treated water. Taste of the water is excellent and the function and capacity of the system are top notch.

        Fantastic system compared to my previous one. The quality, taste, space savings are top of the line. I know my water bill will be less with this unit because it doesn’t use as much when it is purging. So happy with system.

        Game Changer! We now drink more tea than ever. We no longer have to boil water for a bain-marie to make our beloved Crème brûlée. Just a splash of instant hot water while doing dishes means no more waiting for the regular faucet to get hot - saving time, water, and money!

        This is a fine product idea. Getting hot and cold water instantly without need of kettle and fridge is a big blessing for my home since my wife prefers warm water and I prefer cool water for drinking. This has eliminated the need of storing bottles in fridge and use of kettle as well.

        Forget those reverse osmosis systems with a tank. The water pressure is so much better than our old reverse osmosis system with a tank. I have more room under my sink and the filters are so easy to replace. The dispensed water is clear and odorless.
