Easy to install, excellent service and great product so far. If drinking water is a priority for you and family. I recommend this under bench system for its taste and affordability.
Having one internal filter that does three jobs is Perfect and the taste wether warm or cold is exactly what I wanted.

Love this product. It arrived in good time. It was very easy to install – thank you to my son.
The under sink filter system and tap fits well under the sink, is a quality product at an excellent price.
Good flow speed on tap. It is slower than normal household tap, but no one has complained for having filtered water available.
Loving filtered water.
