    A few of the reviewers said that it was noisy. It is, but the important thing is that it does what you want it to do.

    Bought this for my 14 year old daughter who has braces after the dentist found plaque buildup behind the brackets in the back of her mouth. Initial use was very messy...lost of water everywhere. Now that she's been using it her teeth are cleaner and there's still water everywhere, just not as much.

    I would buy it again. It gets all the hard to reach places I can not get with my toothbrush or floss.

    Sometimes food sticks in between my two teeth no floss , toothbrush can help. THIS for sure does! Very easy to use, when tools needs replacement after a half year- just like you replace your toothbrush every half year- it's easy to order and also a discount on it. It's a great, useful product, I suggest to everyone.

    Received product in just a couple days - very prompt service. My hygenist recommended this product. Said it would be a better way of flossing. On the first try I flossed as usual, brushed, then used WaterPik. WOW!! What a difference. Even though I had thoroughly (I thought) cleaned my teeth, the WaterPik got the rest! Amazing product.

    My dentist suggested to me, to purchase a water flosser, so I did. Personally I don't feel it is any better then using string floss. All in all, it is a nice product.

    I had not tried another one, but I like this one. I needed something to replace flossing and I can use warm water or cold, depending on if my teeth are sensitive or not. I like that feature!

    Does a great job, quickly, and without any possible floss cuts to your gums. Should have bought one of these years ago!

    I actually brush my teeth with Sonicare before I use the Waterpik flosser. I couldn't believe how much food particles still remained in my mouth. Every time I use it, I get the feeling that my mouth is professionally cleaned.

    I was never a big fan of flossing and would floss maybe once every other week....until the future called in the form of a water pick. Flossing the old school way is like taking a horse and buggy to work, but I prefer to take my car. Instead of a 3-5min bloody war with your gums, 60-90secs of refreshing water to make your mouth feel like a million bucks is what this water pick offers. Best $50 you can spend on your dental hygiene.

    Had the rechargable model before but the battery only lasted a year. This model much easier to use and flow never fades.

    It is my 3rd Water Pik, and my favorite. Has a real good pressure and starts up as soon as you turn it on. Love it.

    This unit was purchased primarily for our son who has braces and did not like the brush from the orthodontist for getting behind the wires. This unit has an orthodontic tip, hence the purchase. The extra tips are handy since we have two other children. We hoped the gadget factor would promote better tooth care.The unit was easy enough for the kids to get started right away without help. (they kids are 8 to 12) and built well enough that it has survived them as well.The downside is that the novelty did wear off and it has become just another thing to do along with brushing.

    The WP-100 tank holds only 600 ml, whereas other Waterpiks have a 1000 ml capacity. Refilling at mid-use is tiresome and ANNOYING.

    This is my second one of the same model. I broke the hose on the first one and didn't realize you can replace just the hose for a whole lot less. But I found out after I had already thrown it out. I had my first one for 3 or 4 years. I use it at least 3 or more times per day. I floss my teeth the conventional way first and you would be amazed at what flossing misses.

    My wife and I have used WaterPics for over 15 years now. The earlier versions did not seem to last that long. The motors would give out and stop pumping. This model has lasted 4 years and is still going. Gave it to our son and bought this one to replace it. It has served me well in my Dental Care. It is great. I wish it had a little more power. It does a very good job at removing debre between the teeth.

    I eat a lot of peanuts and pistachios. These leave one's mouth filthy. I can brush with my ultrasonic toothbrush, but it does not get below the gum line. With the Water Pik, my mouth gets real clean!

    I love this model. I've been using Waterpik products for some time. This one is very quiet compared to other models. Its controls and storage for additional tools is nice and neat. I am a little disappointed in the amount of water the reservoir holds. It is just a little short of holding the pik about 5 seconds on each tooth. Otherwise, the performance is great, with better control of the water flow than previous models. If you are having problems flossing as often as you should, bleed from your gums, have bridges or other tooth aids that can trap food, I highly recommend you buy a water pick. And make sure the brand is WaterPik they are the best on the market by far!

    This is the best waterpik that we've ever owned. It performs better than the others that we've owned and takes up less counter space. We love using it.

    I love my Waterpik Flosser!!! I am not the guy who will floss regualrly the traditional way, so this has really improved my overall dental hygiene!!! This would be perfect for anyone who has braces and is borderline obsessive compulsive about their mouth..... like ME!!!!!

    I purchased this because I got bracers and I wanted to make sure I cleaned around them good. This product is prefect for that, with the ability to adjust pressure there is no place you can use it. I highly recommend it for not just bracers but to make sure your teeth stay nice and clean. For sure I will use this after I get my bracers removed.
