My only regret about this product is how long it took me to get one. My dentist recommended this to me for many years because of my gums (used to bleed when brushing/flossing). This product is battery operated, has dual pressure, waterproof (in case you want to use during shower) and it does clean deep between teeth and below the gum line, removing harmful bacteria and debris that traditional brushing and flossing can’t reach. I don’t use it daily (although it is recommended), but I do use 3x a week and never had issues with my gum health again! This product is cordless, bringing you convenience, has 2 flosser tips and a limited warranty for about 1 year. Totally worth the price!!! Get you one and you’ll see what I’m talking about.

This device does exactly what it is supposed to do so I am not really grading this on the product itself. I’m taking off a star because the whole process of using this device is messy. You’re going to have mouth rinse all over your hand because there’s no easy way to hold it. If you hold your hand too high, the water reservoir can’t provide water to the pump unit. If you hold it too low, your hand is directly in the path of all the stuff that comes out of your mouth while using it. I do like the battery life though. Haven’t had to change the batteries yet and have been using it 5 out of 7 nights per week.

I am finding the Waterpik Cordless Express easy and convenient to use. Because it uses standard, replaceable batteries (with no recharging), I don't have to worry about re-charging too long or not long enough, and I don't have to throw it away when the battery wears out. Also, because the tank is clear, it is easy to see when there is enough water in it, without holding it up in front of a light source. Surprisingly, the tank closure doesn't leak, even though it is on the side of the tank.Changing the batteries is somewhat of a challenge, because you have to remove the tank (grab and pull down with some effort), remove the cover to the battery compartment (a bit like removing a child-proof bottle cap), figure out which direction each new battery goes in, remember ... MoreI am finding the Waterpik Cordless Express easy and convenient to use.

(If the cover isn't screwed on tight, the batteries won't make contact.)Aside from that procedure, which has to be done after about 40 uses (13 days if I clean after each meal), I'm finding the product a pleasure to use.

On-time, as advertised, overall excellent. Too-tiny gray type ruins the quick-start card, but the full instructions stuck behind the cardboard are fine. The 40-second water time (on low power) implies either a fast pass or quick refill(s). Minor nuisance. Not yet tested on high power, but expect a bit more of the same. This is our second W-Pik. Spouse uses the other in the other bathroom. I really needed a no-plug unit for daily use right on my sink. It fits. I feel improvement in a week. Keep 3 spare AA batteries.
I like this ALOT and it immediately solved a problem area I'd been unable to care for adequately by flossing. I don't have much countertop space for a stand-alone water reservoir, nor is there an extra electric socket available in my bathroom, so having this battery operated option was a real problem solver.I agree with several of the other commenter's suggestions though:1. Would be helpful to have the power button require holding to stay on... would avoid the occasional oops of spraying mirror etc while trying to turn it off. The on/off slider definitely doesnt slide easily and is not easy to operate,2. The stream can indeed be too strong when the batteries are new, even on the low pressure setting. I've cut my gum and/or cheek more than once while transitioning ... MoreI like this ALOT and it immediately solved a problem area I'd been unable to care for adequately by flossing.

The on/off slider definitely doesnt slide easily and is not easy to operate,2. The stream can indeed be too strong when the batteries are new, even on the low pressure setting. I've cut my gum and/or cheek more than once while transitioning from outer tooth surfaces to inside mouth surfaces. I now turn it off briefly to do this when the batteries are new3. The water reservoir sometimes doesn't want to reattach/stay attached to the handle. I initially was removing it from the handle after each use to ensure it drained and dried fully and thereby improve device hygiene. I would prefer to do this but, because of the re-assembly issue, now wait a week or so between fully disassembling for thorough cleaning. Of note: it says the reservoir is top-rack dishwasher safe... true enough but, the plastic becomes very cloudy, most likely due to the dishwasher's hotter than usual water.4. Battery life. The bane of modern life! I like the device best when the batteries are a day or more old so that the stream is not quite so strong. As the batteries become weaker, I just switch to using the higher pressure setting and continue using until the batteries die completely. Dead batteries are the only reason I've found thus far for the device to stop working. The instructions clearly say to lightly lubricate the seal after changing the batteries and I've had no trouble with water getting inside the compartment and fouling things up.5. Some folks thought the water doesn't last long enough. This is true enough with new batteries in the device and used on the high pressure setting. How long the water lasts is one way I use to judge how much longer the batteries will last. Generally speaking, I can clean the outside surfaces of my teeth with one reservoir of water, refill, and then clean the inside surfaces. Using the different tips also has an impact on how long the water lasts. How many times refill is needed is absolutely dependent upon how the device is used, and 'your mileage may vary' as the saying goes.Did I mention that I love this product? lol
This water flosser does an amazing job if used as directed, and removes particles that my normal flossing doesn't get. I use the finer tip for a more focused cleaning and i'm very happy. A couple things to consider are the batteries that come with the unit might be weak like mine were (I replaced with rechargeable) and the tank gets empty fairly quickly when used at the higher pressure. Also you have to be careful with new batteries and the higher pressure because it's so powerful it can make your gums bleed a little and if you move off a tooth it's kinda painful if the stream is on your tongue etc. I have excellent oral health so this is another tool to keep my teeth happy.

I recently purchased the Warerpik Cordless Express Water Flosser following an orthodontist appointment with my daughter. The orthodontist suggested a water pick for her to use with her expander/braces. I immediately went to Walmart and found this water pick (the only one there was to choose from) and headed for the check out. Once in the comfort of my home I opened the package and began the relatively short assembly process. I was able to put the entire thing together from simply looking at the picture on the box. I’ll admit, I don’t have any experience with water picks but how difficult could it be? Once assembled I installed the batteries, filled it with water, and tested it in the sink.

I’ll admit, I don’t have any experience with water picks but how difficult could it be? Once assembled I installed the batteries, filled it with water, and tested it in the sink. This unit comes with 2 pressure settings. Level 1 which is apparently for removing rust and Level 2 which might as well be a plasma cutter. It also comes with 2 heads for the unit. 1 is “regular” and the other “jet”… both are dangerous! After the brief test firing into the sink, I thought I should try it before giving it to my 9 year old. I refilled the water and turned the military grade torture device onto myself. As the pick entered my mouth I used my thumb to activate the pressure setting level 1. I immediately shot my uvula, which not only hurt but caused me to jerk away. By the time I was able to turn the unit off, I had already sprayed my self in the face and most of the bathroom mirror was covered in water. I’m no expert on water picks but I’m not sure my gums should be bleeding… maybe you’ll like it, maybe you won’t… I’m returning this one as I’m not comfortable giving my 9 year old this powerful of a weapon.
Easy instructions and many you tube videos. I am happy.Looks like it is more aimed for customers who are happy with the bigger product but are buying an extra to carry with them when they travel outside USA. I suggest that the product is also aimed towards customers like me who are using this to try flossing. Could have been better if we could choose the nozzle type or options provided to buy extra nozzles at discounted prices. I got 2 off the standard type. I would have loved going for some other types too.
Very disappointed. I have braces and was recommended by my dentist to buy a water flosser to help with keeping my braces clean. I've used the flosser a few times and unfortunately the water pressure is very poor and the flosser is clumsy, awkward and difficult to use. Teeth don't even feel that clean after using and the water tank is far too small. The worst part is that I can't return it because it wasn't purchased in the United States or Canada so I'm stuck with it. Buy an electric toothbrush and use regular floss instead, you'll save yourself a lot of money, time and hassle.
Effective. The process to refill water chamber which must be done at least once each oral treatment cycle and is clumsy. It is clumsy as it requires detachment and reattachment of the chamber to body of device which is not a smooth operation. I would suggest a port on side of water chamber to allow water to flow into chamber either from faucet or a small pour cup. The chamber could still be removable to facilitate cleaning. Aside from this detraction the unit provides good portable function and is operationally servicable. It works.
