Pros: Compact and Portable, plenty of water pressure. Does a better job than flossing. Cons: Multiple refills of the reservoir. at least 2-3 times to Waterpik your entire mouth. All in all a good product.
I recently purchased a portable Water-Pic - 450. This is so convenient for traveling. I still use my regular Water-Pic at home, but I may be converting to using this portable one all the time.
this is my second one. the battery only lasted about two years on the first, and they are not replaceable. but the machine works great, and is worth the price. i use it every night, and it gets so much that brushing misses.
I love using my Waterpik. It makes my teeth feel fresh and clean. It really helps get the food out between my teeth and gums. I can get a little messy with the water going everywhere. But, other then that this is a great product.
