"I bought this in December of 2023. As is typical, the unit stops charging after several months. I had it replaced under warranty and the new unit is doing the same thing. I'm now 2 years out from the original purchase. I keep it in the shower so I can't entirely blame the product, but with the second device, I've kept the charge port covered with cellophane and a rubber band. The issue is oxidation on the charging contacts. As long as it doesn't get rusty like my first one got, you can easily get it to charge by using a q-tip with white vinegar. It's amazing that just a few second treatment does the job. But you have to do it every time. You can actually tell there's an impending problem when during use it starts to flash like it does when it's ready to charge but then shuts off before completing the last use. When it's newer, you certainly have enough power left at that point to make it through the last clean. Anyway, I give it still a four star because it is such a good flosser otherwise. There's no other battery powered flosser with this kind of power, water capacity and portability. What's weird? Is that Waterpik surely knows about this issue and hasn't done anything about it. Wireless charging or even just a water tight cap over the charging port would probably solve the problem."

Purchased at request of my hygienist and it works beautifully. Very easy to use. Just make sure you are close to the sink when using so you're not spraying water everywhere....3ghonda

It's worth upgrading to this model from a less expensive Water pike. The infinitely adjustable setting makes it easier to get the right water pressure. It's easier to hold while filling, and seems to use less water to achieve the same affect, so it doesn't run out before I am finished water-flossing. Also, the on/off feature is easier to use. And the lid doesn't fall down into the water chamber. I like the air vents in the lid, too, as it lets the unit dry out.shopgirl

I started out with a Waterpik Aquarius, which is a very good water flosser. But my sink/countertop is set up so awkwardly (despite being rather spacious) that the electrical cord got in the way, and it was all too bulky to fit properly. Then I got a cordless, hand-held version that was so under-powered and puny that it just didn't do a good job. I hated that one. Finally, the Ion – works like the Aquarius, but slimmer and smaller, and cordless! I've had it for more than a week now, and am really happy with it. I charged it up (as instructed) before using, and haven't yet had to recharge it. It does have a proprietary charger that goes into a USB slot, but that's okay – wish everything could just be a "C" but I get it. It comes with an array of tips, but my dentist told me to use the 'pik pocket' for gum health (and it seems like Waterpik is the only brand with that kind of tip?). Plenty of water in the tank (for two people, even), easy to fill and easy to clean, and I love the way the tubing snaps back into its circular holder. Hope that part keeps working well. And yes, it fits well on my counter, out of the way, with no electrical cord to deal with.van

Wow! Fast shipping! The water pick works great. The unit does not come with a charging wart. I knew this when I purchased it. I used one of my many phone chargers that I have around the house.The pick puts out a strong water stream and works very well.NOTE: There is a mechanical release mechanism on the handle that will release the attached nozzle, be aware of this when using it or it could release the nozzle during use and spritz water all over your hands.linda s

I love my new water flosser. I was pleasantly surprised at how much better it works than regular string flossing. I've always dreaded flossing each day, but water flossing is so much easier and way more effective at removing food particles. I never thought I would hear myself say it, but I actually look forward to flossing now.What Customers Talk About
