great for travel [SEP] i got this for my daughter who has braces she has a much larger water flosser and thought this one would be easier to use and take up less space she did not like it at all so i have been using it this one does take up very little space making it convenient to store or to travel with it is easy to use and does a good job cleaning my teeth however the unit itself is very hard to clean and the tank is a little too small to really do a thorough job so you have to refill it mid usethe unit is cordless which is nice and comes with multiple heads it is easy to re charge and holds a charge for approximately one week overall i think this is a great oral irrigator for travel but for everyday home use i would recommend something with a bigger tank that is easier to clean
