Item : B000EZV6LS Customer Reviews Hopeless & Expensive by .. Jagdish Kumar (Irvine, California USA) Difficult to install. Lack of instructions on how to install. Awfully expensive. Really mad as I couldn't use it even after one month of buying online. I placed order at the recommendation of a friend & now I have a deep buyer's remorse. The manufacturer is not reachable. Oral B ProfessionalCare 8900 DLX OxyJet Oral Care Center by .. John A. Karr () This is my second Braun-Oral B oral care product. The first lasted 15 years. I expect this one to last as long. It makes dental care almost fun! Check it out. J Karr As good as it should, some enhancements onto 7900 by .. L. Wang (North America) There is a 7900 in our house for years, works like a charm. But the tiny pipe for irrigator was cracked month ago (no reason or cause to it, just crack?!). So my wife decides to have a new one, coz it cost $40+ to replace a new pipe for that one (that's NOT an environmental friendly way to push new sales). All in all, 8900 is pretty much the same as 7900. the noticeable difference are two, the brush housing and the control button. 8900's housing looks more updated, fashionable. Though, there is a question about how good it can prevent water gets inside. 7900, on the contrary, wears a rubber outwear covers the button, which looks more water proof to me. 8900 is designed to be able to customize to user's preferred rotation speed. Just press down the button and hold it, the brush will start from the highest speed and gradually lower its speed, release the button at the speed you want it. 7900 has only off, highest and low mode. Great product, well thought out by .. DaveG (United States) I decided to purchase this product after my last visit to the dentist. He said there were signs of gum disease and recommended a water jet type of device as well as a power toothbrush. Well I got both in one unit. I started using it and because of its ease of use I find that I brush and jet much more often than before. My wife also started using it so we have two brushes and two jets. We always remove our brush/jet and store it in the compartments inside the top. I feel that it's more hygienic than just leaving them mounted and exposed to the normal stuff floating around in a bathroom. We both have noticed that the OxyJet really does a good job of getting stuff down under the gum line that is often missed. Looking foward to our next dentist visit (not really). Not Meant to be a WaterPik by .. P. Raftopoulos (London, U.K.) The Oral-B OxyJet is a unique oral irrigator. Most of the negative reviews that it has received have been from previous WaterPik users, who complain about the OxyJet's low water pressure. If you are buying the OxyJet hoping that it will have the same "power" (i.e. psi) as any of the WaterPiks' you will be severely disappointed. The two different devices clean interdentally in two very different ways. 1. The WaterPik relies on high water pressure to remove food debris and bacteria from in between your teeth. 2. The OxyJet uses a much lower water pressure but with the addition of pressurised micro-air-bubbles which "attack" the bacteria. Understand the difference and you can make an informed decision. Personally I prefer the OxyJet, while it is true that on the first initial use you do not get that immediate clean feeling (i.e. a sharp defined edge to each tooth when sweeping your tongue across the back of your teeth) with continuous use (and in conjunction with regular brushing) that clean feeling does come about as the micro-bubbles work on the bacteria and plaque. Whenever I used to use my WaterPik, the cleaning felt very harsh, as if I had just visited my Oral Hygienist, this is not a bad thing, as most people associate that with clean teeth. To me it felt very unnatural and I just could not get used to it. I prefer the action of the OxyJet as it is much gentler and yet achieves the same result and most importantly because I find it comfortable to use, I use it much more often (daily) than I did the WaterPik (weekly). This product is great, because it combines a fantastic mechanical toothbrush with a fantastic dental irrigator in one package, which is very well built and put together with the care that Braun and Oral-B are known for. I would highly recommend this product for your overall dental cleaning needs as it addresses every aspect of tooth-care perfectly. Finally, it would be prudent of me to note that I am not a Medical Professional, dental or otherwise and I have no affiliations to Braun, Oral-B or to [...]
