Why only now discovered, would have saved me a lot :-)

Did I buy the part because I always have problems with food between teeth. Now I can only say was. I am always amazed when spit out what there was between his teeth. The unit also creates beef fibers. What is great still, the interdental spaces are no longer yellow. The only thing that annoys me is that I have the part only now found :-) would have saved me a lot of pain due to dental floss.
