This unit simply didn't work
Again, like the first portable flosser I purchased (and returned) - I so wanted this to work.  Nope...followed all directions to the letter and this unit just wouldn't work. I'm going to give the maker the benefit of the doubt and assume this unit was simply defective but because my need was for a rapidly approaching upcoming trip - I had no choice but to return the item as defective.
