Pros: Portable Three speeds: slow (dribbling), medium (drooling), high (uncontrollable slobbering) Multiple piks and brushes Long battery life Easy to chase siblings out into the hall (old waterpiks with hoses kept water fights confined to bathroom) Cons: Water reservoir is small--constantly needs refilling Extra color-coded piks would be nice Comments: In some ways this is a quantum leap over the old-style Waterpik, the kind with the large water reservoir and hose. It's sleeker, more powerful, and it doesn't tether you to a small space. After all, with that old reservoir-and-hose system, when you sprayed your sister with the Waterpik she could just run out into the hall, and there was no way to go after her as she taunted you from around the corner. This new cordless version solves that and a few other problems. Sadly, it introduces some of its own. Namely: because this device is portable, the water reservoir is small. On 'High' speed (just push the power button once, no need to hold it down) it'll pump the reservoir dry in less than a minute (49.73 seconds, to be precise). But because every action has an equal and ridiculous reaction, be warned: on high speed the water will be pouring out of your mouth so fast you'll need to stand near a sink, ideally with a towel wrapped around you. (Don't get me started on mirror splatter.) Even the slower speeds are rather fast, and if you start wandering around the house with this thing on and in your mouth your family members will flee as you stagger their way, mumbling "water iss onleef neef urrg murpfh glurbin!" before you lurch back toward the bathroom like a gibbering, slobbering baboon. Then they will laugh. But hey, what better way to teach your kids that oral hygiene can be fun, right? After all, it's going to take the little ones exactly .34234 seconds to realize that what you've just told them is a "water flossing device" is clearly a fancy squirt gun. (Silly dad!) Believe me, they'll be fighting over who gets to "floss first" hours before bedtime. But ... at least the reservoir empties quickly. Does it work? Yea. Too well. If I designed this, I'd require the user to hold down the power button (instead of just pushing it once), so when you release it the water stops immediately. As it is now, once it's on, it's on. And if you can't find the off button when your mouth starts overflowing you'll invariably panic. Then, without thinking, you'll take the Waterpik (remember, it's still on) out of your mouth to look for the button, which of course causes water to spray everywhere, including in your eyes and up your nose, until you finally manage turn it off. Or the reservoir runs out. (Which--have I mentioned?--happens fast.) And that sound? It's your family, gasping for air. So there you go. The new Waterpik Cordless Advanced Water Flosser. Fun for the whole family.
