I have a basic Oral-B electric tooth brush and you can actually "pause" it. I gag easily so I sometimes need to turn it off, and when I restart it it remembers where it was. So sometimes I restart it, continue what I was doing and it buzzes after 5-10 seconds because I was almost finished.
If a basic model does it, I'd guess they all do it!
Also don't forget you can ignore the vibrations, just continue after the 2 minutes and count in your head if you need it.
