This is the 2nd one I have had. Loved the first but after a year plus,it died. Could not find a battery to replace so purchased a new one. This one has the two speeds and I really like the fast one; done in about 30 seconds.
I purchased the water pik a few weeks ago. It does a great job of cleaning food particles from your teeth. It is small and cordless which makes it great for traveling.
The water container is so small that you have to fill it up a second time to get the job done. Also the on and off button should be set up that when you release the on button the pik shuts off. Forget and you have water all over the room.
Big, bulky, short battery life and small reservoir will not make it an ideal travel companion despite the advertisement. In a pinch will serve the purpose but not very convenient overall
