Review title is Wrong product sent, but [SEP] First I have to say that I was sent the wrong product model which seems to be quite common, however I decided to keep the model sent and it has turned out to be more than satisfactory. My dentist recommended the oral B electric toothbrush and I can now see why. It does a great job and I am impressed when I brush, it is just like going to the dentist. I will be interested in the comments I get from the dentist on my next visit. This particular model came with two types of heads, has the 30 second timer feature and dual action heads. All in all this is just what the dentist recommended and it has worked as advertised. By the way the product I ordered was the excel model and I received the 7440 Professional.
