Update #2: I know the Pro 1500 isn't on Oral-B's website. When I bought the Pro 1500 nearly a year ago, I asked Oral-B why it's not on their site because I was concerned I had just bought a discontinued product. They assured me that it was in fact a brand new item that they had just released and that they were going to add the Pro 1500 to their site "soon". I realize that it's nearly a year later and they still haven't done it even though they are still manufacturing it, but I have been to their site several times per month since then and I can tell you that I'm honestly not surprised it's not on their site yet. I get the impression that anyone could do a better job with their site up-keep than whoever is doing it now. I have even noticed that it's kinda somewhat falling apart. Some elements no longer work and haven't worked for months. Their products are fine, they just need better people to handle and operate their website. Update #1: When I wrote this review, the price was the same for the Pro 1000 and Pro 1500 (including both the black and white Pro 1000s). Today, the price for the Pro 1500 nearly $20 more than it was when I wrote this review, and currently close to $30 more than the Pro 1000. [Original review below] I bought this to replace a very new Vitality. It was a *HUGE* upgrade over the Vitality, but then I saw the Pro 1500 and learned from Oral-B that it's quite superior. The Pro 1000's specs are: - 1 cleaning mode: Daily Clean - 8,800 oscillations per minute and 20,000 pulsations per minute on the Daily Clean mode - A pressure sensor that's supposed to just stop the pulsations when it's triggered - A pro timer that hesitates the motor once every 30 seconds, and 3 times every 2 minutes - A NiMH battery (old technology) - A battery life of 28 minutes (7 days, 2 minutes per day 2 times per day) - A full recharge time of 22 hours - A green charge indicator LED that blinks while charging, but stays off when it's not charging - A red battery level indicator that blinks a few times upon on/off if the battery needs to be charged - The CrossAction brush head The Pro 1500's specs are: - 2 cleaning modes: Daily Clean and Sensitive - 9,900 oscillations per minute and 45,000 pulsations per minute on the Daily Clean mode (these speeds are faster than any I've seen so far in the specs of any of Oral-B's electric toothbrushes, including the Genius 8000 - they all seem to top out at 8,800 oscillations per minute and 40,000 pulsations per minute) - 7,400 oscillations per minute and 33,000 pulsations per minute on the Sensitive mode - A pressure sensor using a red LED that turns on when the pressure sensor is triggered - A pro timer that hesitates the motor once every 30 seconds, and 3 times every 2 minutes - A Lithium Ion battery - A battery life of 56 minutes (14 days, 2 minutes per day 2 times per day) - A full recharge time of 12 hours - A green charge indicator LED that blinks while charging, but stays off when it's not charging - A red battery level indicator that blinks a few times upon on/off if the battery needs to be charged. - The CrossAction brush head The Vitality is extremely basic: - 1 cleaning mode: Daily Clean - 7,600 oscillations per minute. - A timer that hesitates the motor 3 times every 2 minutes - A NiMH battery - A battery life of 20 minutes (5 days, 2 minutes per day 2 times per day) - A full recharge time of 19 hours - No charge indicators or battery life indicators - Mine came with the Sensitive Gum Care brush head In comparison, the Vitality seems like a cheap generic electric toothbrush. Don't consider buying it. When I upgraded to the Pro 1000, it was amazing. I wanted to burst at the seams and write an extremely rave review, but then I learned about *and ordered* the Oral-B Pro 1500. After using it, I can tell you that the Pro 1500 is *FAR* better than the Pro 1000. I honestly feel the Pro 1000 should be discontinued and no one should ever buy it. I mean really, the Pro 1500 is only $10 more right now and it destroys the Pro 1000. I would have given the Pro 1000 4 stars instead of just 3 if it had a Lithium Ion battery. They charge faster and last longer without charging. So yeah, I am not sure I would recommend the Pro 1000 if you can get the Pro 1500. The Pro 1500 is a much wiser purchase. I'm *extremely* happy with mine. It blows the Pro 1000 out of the water.
