Seems well made, but I don't like the sensation (of a water flosser in general)
Color: Black
This was the first time I ever tried a water flosser, and ultimately have decided it is not for me as I don't like the sensation of water falling out of my mouth while using it. But my mother swears by them, so I will likely give it to her. It does seem to be well-made and of good quality. Even full of water, it is fairly lightweight and easy to hold onto. There are several different strengths/pattern settings, which seems like a good thing. It charged up quickly, but I cannot speak to the battery life as I only used it a few times. I see that the price has dropped by 1/3 since I ordered it.
