“For me, this water flosser is much easier and more convenient to use than string floss, which makes it easier to be consistent and use it daily. And, now that I’ve been using it, my dental hygienist says she’s noticed a definite improvement in gum health. I also appreciate that the company stands behind their product; when I submitted a question they proactively reached out and quickly resolved my concern, thank you so much. I would not hesitate to order from them again.”
