what a great set for my grandchildren [SEP] i remember my own children when they were small and how difficult it can be to ensure they all brushed their teeth at least twice a day and spent a reasonable amount of time doing it i do not try to interfere with how my son raises his children but i gave this to him so his kids my grandkids could have the potential for better hygiene than my kids had i have a similar one that i use myself and think this irrigator is a great way to ensure that they get good reports when visiting the dentist great price for this small portable unit that comes with its own travel bag
