    My previous Water Pik developed a leak in the hose so I bought this model to replace it. Compared to the other model, this one barely has enough power to clean my teeth. I keep it at the highest setting. Very disappointed.

    After a year ot two. Can\'t remember exactly how long I\'ve had it the nozzle breaks or something and it leaks out of the nozzle holder. So I guess I have to go buy another one. [$] is a lot but it does work. Reaches places your toothbrush can\'t get to.

    During a regular visit to my dentist, I was informed that it would probably be better for me to increase my dental checkups because of excess plac. Using the water-pik I purchased from Target, my Dentist has informed me that my plac problem has been tremendously cleaned and under total control. It will be an intergral part of my dental process every day now. Armed with my toothbrush and water pik, coupled with regular dental checkups, I feel my teeth are cleaner then they have ever been.

    It's a great little machine if your kids will use it. I bought it about 5 months ago and everyone used for the 1st month. I am surprised if they use it even once a month now. It was a recommendation from the Orthodontist.

    This product does the job, no doubt about it. I fully endorse the waterpik WP100, except for two problems: 1: they do not last long, and you cannot repair any part. The nozzle head begins to leak, dribbling down your hand until you give up and buy a new one. We have bought five of these in about 7 years. Seems like they should last longer. 2: waterpik does not distribute to stores the nozzles that wear out, the ones most commonly used for really good gum cleaning. They supply one with some models, and you have to buy them online at waterpik or other outlets. The nozzles you get with the machine are the very hard plastic tipped nozzles with the half life of cobalt. Your grandkids will still be using them, but you get a handful with the product. The really good ones have to be bought separately.

    absolutely love it. what I really love is that my 9 year old son uses it and really likes it, he was cavity free last dentist visit. My mouth feels wonderfully clean have had it for a year and the dentist was amazed at how little I had to have my teeth cleaned. I use it with a little bit of listerine in the water at night and I wake up with absolutely no film on my mouth. I have a bridge and it is amazing how it cleans in between it and my teeth in general. Highly recommend it to everyone especially if you have a permanent bridge or braces. It is my xmas gift to my love ones this year. Everyone is getting one.

    The Water Pik works great if you have braces. I use this now instead of flossing each bracket.

    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.

    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.

    If you want to do the extra bit to make sure you have flushed your teeth and gums as much as you can after flossing, this device does it well. It's the best one for the money spent.

    This machine is awesome! I still floss with regular dental floss before using, but after using the water flosser, my mouth feels so extremely clean! I mix Listerine in with the water, and it makes for some amazing smelling, and long lasting breath!

    My dentist uses this method to clean my teeth every several months so I picked this up to see if it will make an improvement over regular flossing.

    I got braces recently and bought this product to help with cleaning. It has been a godsend. It cleans everything really well. There were 2 different models when i bought this one. The other model had a larger water reservoir. I will tell you that this one has the smaller reservoir, but that doesn't matter. Most of the time I still have water left over after I've cleaned all my teeth, so the larger one is just throwing money away. Great product. I would recommend that you lean over the sink and point your mouth at the sink or else your bathroom mirror will get a good washing from the overspray.

    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 periodontist recommended the Waterpik and I've been surprised by how well it works! Great product and I can see the difference in my gum health

    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!

    Product works well, but water tank is too small. It cleans teeth and gums well, but the tank does not hold enough water. It must be refilled to complete the job.

    Very good update to the water pick and floss combination. Much better access and nice design.

    A previous reviewer gave the Ultra Water Pik one star because it wasn't powerful enough. I cannot imagine how this could be true. I suppose if you were trying to cut metal with this Water Pik, it might not be "powerful enough." Basically, even if you are on setting 5, this is more than enough to do the job in cleaning your teeth. The Ultra Water Pik works very well to flush out debris from between the teeth and gums and only after a week of use, my gums appear to be healthier. My dental hygienist recommended the Water Pik to me and it has proven to be very effective.

    Big improvement over previous models. Pros: Storage in lid prevents clutter; self-curling hose makes replacing tip a snap and looks neater. Actually, this model is very streamlined and not as unsightly as previous models. If Waterpik would find a way to allow the user to stuff unused electrical cord length in back of the model, it would be nice. Tip. I find that wiping out the basin after each use keeps it looking brand new, especially if you have hard water.
