Question: Can this product be attached to a sink?  I am looking for a pulsing flosser that attaches to the sink.
Document: This is the very first time in ten years that I have returned a product, usually I work my way around it or give it away. Returning a product takes time too. I had heard of the product name before and looking at the price, I felt that it had to be of some kind of quality level. Well... I truly got fooled by the companies marketeers, and will avoid any future products with this brand-name.
this product is great, so easy and convenient it has turned me into a daily flosser, my dentist and hygenist will be happy!! !
The only downside to this product is that it is very cheap looking. If you're going to install it in a nice bathroom...be prepared. The connector piece appears to be made of some kind of plastic that is painted silver which looks terrible in a nicer bathroom.This device is super convenient. You'll never forget to floss since it is just so easy to do while you're in the shower. It is very powerful and since I was a new waterpik user...I made a mess the first time I attempted to use it :DThe charge seems to hold for weeks at a time.
I would not buy this product again and do not recommend it. If you want to use a power flosser in the shower, buy a regular waterproof one and just carry it with you into the shower. This way, you also have the option of using the reservoir for mixing solutions and medicated washes/rinses, etc., which is impossible with this unit. **Update**Waterpik customer service and warranty were outstanding. I sent an email detailing the above problems, then I called to ask a question which, incidentally, some of you may be interested to hear so I'll mention it as a tangent.
Once installed the product works great. I really wish Waterpik would have spent a little more money on the connection components. The unit itself is great and it has that quality feel similar to our Sonicare toothbrush but that is where the quality ends. The unit attaches to a plastic tube; to a plastic connecter; to a plastic joint; to a plastic bearing that screws onto you existing shower head pipe. People who are not that handy or not used to tightening plastic components onto metal fittings may end up breaking the product.
This was so easy for my husband to install! No extra parts needed, just hooked right into the existing shower head. Also, this works amazingly as a flosser. My breath has never been better (according to my husband). I only use this now, no flossing any more!
This water pick is the best because you do not have to deal with the inevitable &#34;Water Pick splash fest&#34; on your mirror and sink. It did not change my water pressure at all. The shower head sticks out an additional 2 inches or so, but that's really nothing. The hose is nice and long so I can pretend its a microphone and rock out after it cleans my teeth. It also doubles as a watergun. A great way to surprise my girlfriend when she is in the bathroom while I'm in the shower.
After only a couples months use the water will not stop squirting out of the waterpik even though I it's turned off. The water will only stop once you turn the shower off. It still works and I do love it, I just wish I could figure out why the water continues to spray even though I've turned it off. It's just a pit of a pain.Great results from the dentist though and I wouldn't go a day without using it. Also nice is you don't see all the junk falling out of your mouth into the sink!
My dentist told me I would never win the Olympics of flossing. He said my lack of flossing was damaging my gums. When I saw this Waterpik that hooked up to the shower I knew I had to try it. I used to have a Waterpik on my sink counter-top but it took time to fill the reservoir with water before each use, and then to clean it out after each use. It was quite a hassle. This is hassle free. I have used it everyday since I received it because it is so convenient - it's always ready to use.
I bought this after reading all the reviews. It was easy to install, and it works great when it works. The 2 speeds are easy to select (despite the other review) and they are different but not extreme (despite the other review). Both speeds work and neither speed hurt my gums. I use it daily, which is why I purchased this model of flosser. I have the base unit, but didn't like having to fill the container, and sometimes wanted to floss longer than the water supply provided.
