I have been using these Oral-B "complete" toothbrushes for several years because they are the ONLY brushes I've found with a small enough head to comfortably maneuver around my mouth due to my very narrow jawline. Not only are they are comfortable in my mouth, but perhaps the best part about them is (a) the shape of the handle in my hand, as well as (b) the non-slip grip of the material they use on the handle. Other Oral-B brushes don't have that grip texture, and when your hand gets wet while brushing, the brush continually slips and slides out of your grip...and that inability to firmly grasp the brush can cause slippage (and injury) in the mouth as well. THESE Oral-B brushes are perfectly designed and I hope they never stop making them!Side note: these brushes have become very hard to find at local stores -- in fact, virtually impossible to find! About a year or two ago I decided to search Amazon for them and THOUGHT I found them because the description was "Oral-B complete" and the picture matched exactly to the design I was looking for. I ordered several of them in the hopes of stocking up for future continual use (in case Oral B ever stops making them), but unfortunately I had to return them all because the brushes I actually received DID NOT AT ALL match the description of what I thought I was ordering. That incorrect shipment was awhile ago though.Last week I decided to search Amazon for these brushes again and, sure enough, the picture again matched exactly to the properly designed brush I've been looking for. With some apprehension I decided to take a chance and ordered two packages of them (6 brushes each) again in the hopes of having success the second time around (wouldn't have tried again if not for Amazon's easy return policy...just in case I received the wrong ones again). I'm VERY happy to report that -- YAAYYY! -- I received the package of 12 and THESE brushes are indeed the EXACT "Complete" brush that I've been hunting for. Needless to say, I promptly ordered two more packages to stock up, so I now have about a year's supply! My mouth is happy again, I thank the seller for actually selling and shipping what they advertised, and if you decide to order them you can rest easy knowing you'll get what you think you're getting. Enjoy!
