Great product an even better customer service
The product is great and water taste amazing. I would highly recommend to everyone concerned of their health and the environment. In addition to this, the customer service is really exceptional. They answer immediately and support all your questions and doubts. Great company overall. It is a real pleasure to work with them.

Membrane replacement impossible
Terrible experience and completely user unfriendly! I regret that I spent so much money on this unit. Not only is it expensive to maintain it by purchasing costly filters and membrane but it’s practically impossible to disconnect the old and insert the new ones. Even with 2 people pulling and pushing elbows, tubes etc. Extremely counter-intuitive and hard to use. Never again!
