## Description

The Waterpik Cordless Plus Water Flosser is a great solution when you want the convenience of cordless water flossing. Rechargeable and portable, it's perfect for use in smaller bathrooms or for travel.

Review: Works exactly as advertised - Used one of the original plug-in-the-wall Pik units back in the '60s as a kid. Considered it a chore. 50 years later, with gingival issues, I didn't realize then how important it was. The PLUS is a great product. Battery good for about 2 weeks of use (once with regular tip, once with pocket-pic, daily,) and a large enough water reservoir. You can safely ignore the poor guy who complained about the tip "spinning around" because he was too ignorant or stupid to actually insert the tip into the unit properly. I recommend it to everyone. Gingivitis (which affects almost everyone, eventually) can lead to increasing pocket depths, which contributes to bone loss, which, if bad enough, will lead to tooth loss. Those scary pamphlets in your dentist's office have a valid point. Not a good road to go down, unless you admire the toothless hillbilly look. There have been many published dental studies (I read about 40 of them on-line in the Journal of Periodontology) that confirm the efficacy of disruption of bacteria whether physically or chemically (by, say, chlorhexidine,) and the PLUS (and Pocket-Pik tip) are good tools in that ongoing war. Cheap at twice the price, but don't use it to remove ear wax (one study details how you'll rupture your eardrum.) Update: After about a month of use, it seems to be consistently good for about 2 dozen or so uses between charges. Speaking of charging, someone commented about corrosion on the charging contact pins. It's true -- I noticed minor corrosion almost immediately. It would have been better if Water-Pik had provided some sort of plug/barrier to keep water out of the plug-in cavity, or, better yet if they had used an induction-charge system with no contact points or pins as do many electric toothbrushes and other devices (either would make the product slightly more expensive, the later more so, but it would be well worth the extra dollar or three.) But, unfortunately, they didn't. Nonetheless, the corrosion problem is easily solved without buying any Radio Shack parts. Carefully scrape any minor corrosion off of the pins with the tip of a knife and use an inch of tape (anything that's about 1/2" wide) over the plug-in cavity to keep water out of the plug-in cavity while in use between charges. Hopefully, they read this stuff and will either add some sort of (attached to the unit) plug or go to an induction-type re-charge method on the next version of the PLUS, if they haven't already concluded that one or the other is a good idea. In any case, I still HIGHLY recommend the PLUS. It gets all sorts of stuff out of your mouth that brushing and flossing can't and don't.
Review: Good news. Just spoke to Waterpik. They will replace the leaking part for free (One day out of 2 year warranty) - After 2 .5 years the battery gave out. Because how itwas listed when you put Waterpik into the search boox, a different irrigator is snuggled in below the waterpiks and says its the NEW AND IMPROVED version MISLEADING one to believe it is also by waterpik. I fell for it and after ordering it was dissatisfied. I chatted with desertcart and they said they would send me a new waterpk on SAME DAY SERVICE at their expense for the confusion. I am so pleased with my ointeractions with desertcart on EVERY LEVEL (been with them for 3 years now) that I can not recommend the company more highly!. The new waterpik arrived 17 hours after talking to them (desertcart) and I now have the product that far outdoes the "new improved" model by another company. See my review of their item. It's great. I now mix the mouthwash I use in it with water (seems a 50/50 blend works fine) and it delivers as advertised. It runs long enough (ample amount in fact since I often have contents left over) Is light and maneuverable has 2 power ratings although I only need the hi setting. When I take it off the charger it seems to run forever! I left it off for over 3 weeks and it never stopped working. I put it back on the charger since my other items on my 2 outlets thinned out so I never did find it's maximum battery (non ac connect) point. I think I will recommend this battery to TESLA. I guess my only silly issue is how they created the hole stopper where you put the liquid into the holder. It works fine, don't get me wrong. But once you buy it, it LOOKS as though it will come open. (IT NEVER HAS) which is somewhat of a miracle of design Perhaps I should simply change my rating to 5 stars....lol Well the replacement came through and it does not leak. I am very happy they did replace it because when it coincidentally started dripping two years to the DAY (on a Sunday) that it was covered for on a 2 year warranty that I had no idea was in force, the kind lady at Waterpik realized how close I was to the deadline that she simply replaced it. I didn't even have to tell her that I tried first desertcart on Sunday who advised me to call Waterpik first in order to get this resolved. So as far as Waterpik knew, I was one day out of warranty and I didn't bother to tell her that I DID try on Sunday but they were closed. I feel good about them backing their product like this. However, when I asked if the replacement also had a 2 year warranty on it, she sadly said "no". ++++++++++++++++++++++++ Evidently I have had this 2013. As of today FEB 2016, THE BATTERY FINALLY STOPPED.I SEE ANOTHER PERSON RAN HIS FOR 8 YEARS. THIS IS ONLY 3 PLUS YEARS. I WILL LOOK INTO REPLACING THE BATTERY AND SEE IF THIS IS A BETTER SOLUTION THAN BUYING A NEW ONE, SINCE THEY HAVE UPDATED THE MODEL. I WILL RETURN AFTER INVESTIGATION.

## Questions & Answers

**Q: Is there really enough water to fully brush?  Is the floss head as floppy as many claim?**
A: I have the WP Flosser-450, portable, no batteries. Very happy with purchase and WP gives it a 2 yr warranty.  Amount of water depends on persons preference. The reservoir holds about 7.6 ounces.  Sometimes it is enough for me, sometimes it isn't.  But no worry since it is really easy to fill it again and double your pleasure.  My floss head is secure and strong with more than enough force I need on setting Low.  I just tried setting High and it is secure also.

**Q: What is the Power supply:Input: AC 100-240V ?? 110 VAC only?  Thanks.**
A: The power rating is 100 to 240 VAC. This means it works on 100 -120 VAC mostly in USA or 220- 240 VAC mostly in Europe. Kind of like a cellphone charging block, works on 110-220 VAC

**Q: Is the waterpik water flosser cordless plus compatible with 220 voltage?**
A: No.  You would need an adaptor.

**Q: voltage of the recharger?**
A: This is what is says on the AC Adaptor charger: Class 2 power supply  Input 120 V  AC 60 Hz  2.1W
