Hot Portable Power Floss Dental Water Jet Cords Tooth Pick Braces No Batteries
No even a toy water gun quality
I was expecting it is like a toy water gun. That would be enough for casual teeth cleaning. But it like eye drop. Totally useless. Very bad quality. Threw to garbage can five minutes after its arrival.
DuPont Kevlar® Thread (TEX40) 100-ft Black Strong Heat Resistant
Strength just like cotton thread
The one I received has no brand and just wrap in a generic cheap plastic bobbin. The strength has no difference from cotton thread not even close to Kevlar Thread. Burning it does not smell chemical burning, just like cotton burned.
