Good for travel. Great value.
This cordless water flosser is strong enough to remove stubborn particles from between teeth. I can go more than two weeks on one charge.  It takes filling the tank twice, sometimes three times, to do a thorough job.  However, if it had a larger tank it would be difficult for travel and awkward to hold while flossing. I don't believe this would be a replacement for actual floss but it does clean well.
