I like my new Water-Pic very much! It has strong action, it's easy to use, compact, and seems to have an excellent battery.I'm still using it on the initial charge. That was at least 2 weeks ago, if not more, using it every day, sometimes twice or more. It also holds enough water to last for a thorough, basic cleaning. Using this device is easy and comfortable. Its small shape fits easily into a counter space in my small bathroom.
