neat concept could be executed better [SEP] i really like the idea of a portable water pik when i travel i have to pack up my standard water flosser and it is kinda bulky and does not travel well so having a single integrated unit is appealinghowever the implementation is a bit weak for starters the tank is either glued or heat welded along its entire perimeter and it will i am sure be a weak spot that eventually leaks as you use it since it is all one piece it is really hard to hold on to and the water runs directly down from my mouth on to the unit making it even more slippery maybe the pik head should be angled to allow for the water not to run down on itif you are someone who travels a lot and you need to have a water flosser with you i think this is worth a try with some practice it might become less awkward to use over time
