Prompt action on faulty battery life.
I have had other hand held flossers, which I did like.  What a particularly like about this one is its large capacity water reservoir and the intensity of the water stream.  I found that the various tips that come with it are very useful for my particular issues. Most important to me was the prompt, personal reply when I reported that that battery wouldn't charge.  Suggestions were made to remedy the situation but also included a no questions asked replacement.  I am delighted with the quick and personal customer service.  I feel confident that, should I have another issue, it would be addressed and rectified quickly.
