This is the first waterpik I've ever bought. My dentist recommended that I use one, so I chose this model because it is a smaller one. I like how easy it is to hold in my hand and manipulate. I'm amazed at how it cleans my teeth, and how my teeth feel better after using it. Since this is a portable model my husband (who has also started using it) and I are going to buy a larger unit and keep this one for when we travel.
Have had a few waterpicks. Love that this one is waterproof and can be taken into the shower. I find the pressure just fine at the lowest setting. It is easy to fill up.
Easy to use & gets the teeth clean. However, this device emits a high RF level (radio frequency) when used. It's like putting a cell phone inside your mouth/skull. No wonder why there is so much cancer these days!
