Great customer service
I bought the H20floss in October, and really fell in love with it.  It's very thorough and effective.  After 3 months, my unit started to malfunction where the water wouldn't come through the plastic tip.  I wrote the company, and received a response the next day!  They apologized and sent me a NEW unit which came within a week.  I'm very impressed with the company and the product.  Great customer service!!!
