Having used one of the first Waterpiks for over 10 years, I settled on this one hoping to be able to use it when traveling, especially outside the US. This unit suggests recharging the battery every week, which is okay for shorter trips. However, the water reservoir only holds enough water for approximately 2-3 passes of the 4 necessary to process all the tooth-gum junctions. There are only two pressure options and the tips seem to have short lifespans
Good for use in shower and on trips. Cleans well but 1 tank of water covers the inside of mouth, then needs to be refilled for outside of teeth. Top heavy---bottom should be square and wider than top. Tank should have a way of staying open to dry out between uses.
Good product I take it in the shower in order not to make a mess. Seems to do a good job and I will know if it does when I go back for my next cleaning in a month or so. I use it 2 or 3 times a week.
First one stopped charging and got it replaced. Bought for it cordless features. But pressure can not be regulated much so a concern that it too much pressure for my gums, also pretty messy when using, even after much practice. But not too many cordless choices out there.
