You just can't leave home without it. I bought it on vacation because I hate to floss and found this portable water pick to be perfect. Now I don't just travel with it but love to take it to work and use it after lunch. The one thing it doesn't have is a charging light so you never know if it's fully charged or not. So this part is a guessing game.
Well it's not very easy to use the water goes everywhere high pressure not very impress with the water pit I m sure if I take it to my dentist it will be a very useful instrument,
