        Rodi system was package nicely. Directions are easy to follow. Would like to see more information on the start up. Does it have to be cycled first?


        Their products are genius!!

        Great Product

        Got the delivery in record time, 3- days, installed it and now its working perfectly. I love the design where it keeps the media wet and charged when the reservoir is full.
        Ideal product for RODI water


        Thanks for taking the time to review our Performance Plus RODI! The unit will serve you well and the most you'll have to do is change filters! The system does the rest of the work such as tap flush, pure water flush, and production. Keep in touch if you need anything in the future! Thanks for supporting Small Business.
