My last plug-in model felt like someone tugging at the coiled cord. This model has enough power, takes up less space on my sink, and surprisingly does as well as the plug-in model waterpolo that served me well for about 10 years. I would highly recommend it. I hope it lasts for at least 3 years.
I bought the 360 about a month ago... I use it every nite; this product realy works. I have seen good improvement in my overall tooth and gum appearance.
