I have owned the Philips Sonicare Elite 7300 Electronic Toothbrush for several years now. It took me awhile to get used to the vibration--for the first week or two, the vibrations really tickled my teeth and made my nose itch, but I got used to it eventually. The toothbrush conveniently has a button (the small gray one) that switches the toothbrush from a higher power/intensity to a lower power, so if the intensity of the toothbrush is too strong for you, you can turn it down. This is especially helpful while acclimating to the change from a manual toothbrush to an electronic one. I don't use the lower power at all anymore. The toothbrush has a column of green lights that indicate how charged it is. While charging, the lights blink up and down. The battery has a long life, but now that I've used it for several years, it doesn't last more than a couple days between charges so if I go on vacation I have to bring the charger. Also, crud accumulates in the well underneath the replaceable brush head, and it is difficult to clean it out.
