Review (4/5): Great for travel!
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 didn't like it at all, so I've 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 use.
The 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.
