Summary: unlike other travel irrigators it uses replaceable batteries which is far better than the NiCd rechargeables which seem to lose their potency if not used regularly. The function of the irrigator is excellent.
Summary: Excellent Battery Powered Oral Irrigator that allows you to replace the two AA batteries when needed. Other irrigators on the market have non-replaceable batteries welded within their units that must be recharged with an adapter - but once the battery reaches a certain number of recharges the battery weakens and the unit is useless.
Summary: Great for travel or at work since stores completely within itself. Although not as powerful as the cordless Waterpik, it's an awesome alternative. Runs on 2 AA batteries. Reservoir removes for easy cleaning too.
Summary: I bought this oral irrigator upon recommendation from my dentist. He has one and said he uses it everyday. I like it. It has a good strong stream of water. I love how it feels on my gums, just like a massage for my gums. I gave it 4 stars instead of 5 because I still have to floss my teeth, which I hate doing. But, overall it does a good job and does get some things off my teeth.
Summary: This is the first oral water irrigator I have ever bought. I am pleased with its small compact size and its collapsible water tank. The noise is not loud or annoying at all. I need 2 full water tanks to clean up my entire mouth, using the level 2 power. The irrigator is easy to hold and use, but I had some trouble opening the battery lid with a coin (it stops at one point without opening the lid, so it needs to be twisted further more, and aligned with the marked dots).
