Tried and True Design:
This used to be the epitome of electric toothbrushes. It seems to me, the patent should have run out on this, which makes me wonder why other manufacturers aren't using this design. But then, I think most of the other brushes are just gimmicky, and they'll come out with another gimmick in a couple of years to keep "improving" their design. Using this, after using other toothbrushes, you can notice the difference. You can FEEL the penetration between your teeth. And as another reviewer said, you can see the difference in the sink. I notice much smaller particles coming out. The twisting tufts can get around and in everywhere, from every angle. What else surprises me is the price. The first one I bought years ago was around 80 bucks. I imagine 80 bucks would be considerably more, today. I'm glad these are still available. I started looking at the other, more expensive brushes and was prepared to buy one, when I thought I'd do a search for Interplak, and I was pleasantly surprised to find it available for THIS price. I've had several of these. One of the reasons I had several was because the C cells do, eventually give out. I did replace the cells one time, but found that, with all the gyrations this thing does, the parts in the handle eventually wear, so you might as well throw it out when the cells die, anyway (much easier at this price). I noticed, another reviewer had a good suggestion of charging the unit, only when necessary, to prevent the memory condition that plagues most rechargeable cells.

Best toothbrush ever!:
This is the best electric toothbrush available, except for the poor quality rechargeable batteries. The unique design allows for cleaning in even the smallest spaces and under the gumline, too. My hygenist is always amazed at how free my teeth are of plaque. I attribute it to this toothbrush which was recommended by a periodontist many years ago, and I've used it exclusively since. I really hate to give it 5 stars, because it is annoying to have to buy a new toothbrush every year when the battery gives out, but its superior cleaning ability cannot be denied.

Best Model Yet:
I bought my first Interplak toothbrush in 1990, as recommended by my orthodontist, to help me clean around my newly installed braces. Worked great. I have used an Interplak toothbrush daily since then (~18 years). When the battery eventually died in my first Interplak toothbrush, a new model had been developed, the model 12207, which I bought for my second Interplak toothbrush. It's battery finally died recently. And now several newer models have been developed. I chose the model NT7CS as my third Interplak toothbrush. So far, I am very happy with it (I've had it for a couple of months). The model 12207 had two head sizes: one seemed a bit large, the other too small. The new head for model NT7CS seems just right. The model 12207 lasted significantly longer than my first toothbrush. It remains to be seen how long my model NT7CS will last. I recall in 1990 using Interplak-brand toothpaste with the toothbrush, but only for awhile, until the first tube ran out. If you are a first-time user, you will probably want to use toothpaste also. But the Interplak toothbrush does an awesome job without toothpaste. As I've moved around, each dentist I've gone to has commented that there is practically nothing to do at my teeth-cleaning appointments, and that my gums are very healthy. (Perhaps the hydrogen peroxide rinsing I do is partly the reason.) Anyway, be aware that if you use toothpaste, your toothbrush will have to work harder, and your toothbrush's battery will drain more quickly. So you'll have to charge your toothbrush more frequently, and the battery will die sooner. You can keep the head "fresh" by pouring mouthwash over it from time to time when you finish brushing. Also, remember not to keep it on the charger continuously. Charge it up, and then use it over the course of several days until it runs out of power, and then give it a full charge again.

Great Product:
I have owned several of these Interplak toothbrushes over many years so you can guess that I love them! If you have anything wrong with the toothbrush, Conair takes care of the problem easily and swiftly. The only problem I have had with the unit was when it was brand new. But if they worked perfectly in the first month they all lasted for several years. To let you know, I have also owned a SONICAIRE and all I can say is, what an overpriced, overhyped piece of garbage. The Interplak gets rid of the plaque and the Sonicaire never touches the plaque. In addition, the Sonicaire makes a real mess as you're brushing by flinging lots of the toothpaste all over the bathroom as you brush - it's pretty gross actually....and if you accidentally touch the brush head to your teeth it really hurts and feels like it will chip or crack your tooth! The only thing you need to be careful about with the Interplak is the toothpaste. The grittier the toothpaste, the faster your brush head will wear out. Not the bristles but the internal gears in the brush head. Gels are best, but you can use regular creamy toothpastes regularly or intermittently. I don't know why Conair doesn't do a better job marketing this product because it is my favorite hands-down over Sonicaire and the other electric toothbrushes I have tried.

Got my money's worth after 3 years of use!:
I've been a long time Interplak user, and truly believe that no other product can come close to the thorough cleaning of Interplak. My dental hygienist can tell when I've been using another type of tooth brush. No other toothbrush has a design that can get deep in between teeth. I had this model (NT7CS) for three years before it needed to be replaced. For a $20 investment, that's good enough for me. The biggest complaint in the reviews I read when I initially researched it was that over time, toothpaste residue would build up in between the ridges of the rubber handle - and it does. But it only takes a minute to clean the handle with a brush that has stiff bristles. I recently replaced it with a newer model, Interplak DPI9R Direct Plug-In Rechargeable Power Plaque Remover and would recommend shelling out the extra money as the DPI9R has a much stronger battery and cleans more powerfully on its high setting than the NT7CS.
