Great flosser at a good cost.
I have been using flossers for many years and have tried many.  In my opinion they all have a "shelf life" of about 3 years. Even Waterpik brand, which I'm not that crazy about for its size and cost. So I started trying unknown brands.  I like this one.  It has a tank large enough for one full floss cycle.  As for filling that tank, you have to detach the top from the tank.  Other brands have a side hole.  This is not a huge issue but requires getting it sealed up tight after you fill.  I think it is powerful and does a great job.  I love the size.  Just an observation if it should matter to you:  the top is not a pure white. When I opened the box I thought it was gold. It is more a pearl white/gold/silver.  Depends on the light.  Not a big deal.
