I got my Flaus via an IndieGoGo campaign -- I was excited about a product that is eco-friendly and help me to floss better. The floss thread didn't glide through my teeth effortlessly as advertised and the thread snagged and broke before I got through half my mouth. When I went to replace the floss head, I accidentally tugged on the stem and dislodged the tube from its outer casing and the plastic piece that is the "on/off" switch got stuck. In the end, could not get the plastic piece back in and now it cannot turn on. Emailed the Flaus customer support a few days ago with description on what happened and photos and no reply yet. Not even an email acknowledgment that they are looking into it. And their online chat does not work. I bought tons of extra floss heads during the campaign so now it's just a manual pricey floss pick. Totally disappointed at the construction of the item.
