We purchased 3 Air Water Generators model c21 and got ripped off! This company refused to send us repair parts under warranty, and gave us one excuse after another and dragged this matter on for almost a year. Since we are in Saudi Arabia, they figured they will get away with it. This conpany has made false claims about their equipment quality and their promises of support. Beware of dealing with this company. We have written proof of their dishonesty, and if anyone wants it to support their legal claim of how dishonest these people are, just ask us.
