This product is really compact yet holds a good deal of water for daily flossing. Decent water flosser.

A few weeks of use created ugly and noticeable brown stains near the charging port. There is no indicator that shows when the device's battery is fully charged. Seems they spent more time trying to renege on the warranty.

Hard to fill water reservoir from average bathroom sink. Unit is defective out of the box and does not build pressure unless the tank is full. This means you have to refill it several times during one use.

Don't waste your money. Don't be fooled. Sincerely regret getting this unit. I sincerely apologize.
