An Evolutionary Upgrade That Pays off BIG
I've used Oral B toothbrushes for years now. I have always been more than satisfied. I purchased my most recent professional series over 6 years ago. I've always watched them and from appearances, nothing seemed to change. I was wrong! When the brand new 4000 series came out it piqued my invest. I bought one at announcement and when I opened it I was pleased by several differences:<br />1.  The new  spare toothbrush holder is better thought out and works much better than the old 'stand up' one.<br />2.  The charging base itself is flatter and more attractive.<br />3.  Unlike the old charging base, there is no where for gunk to pool and become unwashable. Sounds like a small thing, but who wants to look at a mess on their kitchen counter?<br />When I used it I found out that the improvements were more than skin deep. This is a better toothbrush. I cannot quantify it, but it does clean better, not a little bit, but a lot. In addition there were some positive functional changes.<br />1.  The standard two minute cycle with beeps every 30 seconds has been augmented with a ' deep cleaning' cycle that simply uses the same brushing action with a three minute cycle and beeps every 45 seconds.<br />2.  A separate polishing cycle has been added.<br />3. A sensitive cycle has been added. For people first converting to an electric toothbrush, especially kids, this is a plus.<br />4.  A pressure alarm light that is easily visible has been added. This was a plus for me since I saw that I had been brushing too hard at the very back of my gums.<br />Is this an entirely new and revolutionary product for cleaning your teeth? No. Is a very real upgrade resulting from refining that which was already good? Yes. If your Oral B is several years old, you may want to consider upgrading.
