I'm not really a product raver but this purchase has actually changed my life. Orally anyway. It's so easy to use, it's cheap, considering what it does. I don't know why the manufacturers don't advertise on TV. They would make a fortune.
The jet stream is more powerful than the average electric version. There is no hassle with plugs or with what liquid you use. Water, salted water, bicarbonate of soda water, medicated liquid, whatever. Just pour your liquid of choice into the compartment(the hand held part). Twist the top on (the section with the blue button and nozzle, place nozzle where requierd and pump the blue button. That's it!
Easy to rinse plastic. Gives a great stream. When empty just do it all again. You get a good flossing in one refill. You can carry it anywhere with no fuss. It's the best purchase I've made in years. Why does no one know about this gadget?! Try it.
