Makes mouths happy!
I use my PHilips Sonicare 3 times daily and I love it. It is much easier than the standard toothbrush, and leaves your teeth feeling great!

Compared both models, e3000 a bomb (not "the" bomb, but "a" bomb)
Too many reviews;
I'll do this one in Haiku!
Let's dive into it.

Saw all prior views
of Sonicare customers
Amazon provides.

Key to the debate:
whether cheaper is better,
or price wins the day.

Higher on dollars --
e7300 ("e seventy-three hundred") --
link given below.
Philips Sonicare Elite e7300 Power Toothbrush

Then there is this brush.
Cheaper, with features to match
(save only a few).

We bought both brushes,
one each for my wife and me.
Experimented.

Used both Sonicares.
Brushed ev'ry night, she and I.
Same treatment, same care.

Endlessly we sparred.
Three months later, here we are.
One emerged victor.

Three months was too much --
for the cheaper brush was crushed.
Suddenly it died.

No water damage,
no mishandling, no neglect.
It just died -- kaput!

Here is my advice:
for relability
shun the cheaper brush.

Yet consider this:
THAT costs three times more than THIS.
It should give you pause.

Seems the math is thus:
THREE times failed before we must
declare one the best.

For is this not true:
fail three times before I do
end up losing out?

The price of one though
more reliable, cannot
beat the other's cost.

Friend, it's up to you.
Buy the best or try for two;
Less than three duds wins!

Improved Model
I read some of the reviews before buying this Xtreme e3000. Phillips must have made improvements because I have used it over a month now and no wear or corrosion evident. I consider it a good value compared to the other more pricey models.

long-term review -- fantastic product if you take care of it
Great product, and there's no problem with the batteries if you take some minimal care. Read on...

I'm a traveling consultant, and I've had two of these 3000-series toothbrushes over more than a hundred trips over the past two years -- only because the first was damaged during a trip to India. I stopped using my previous regular Sonicare unit because these work very very well, and with a pair of rechargeables, I get the benefit of both worlds.

Power and performance -- The brush head action feels the same as my older Sonicare. This is to say, strong and thorough with no complaints at all. The 3000 has a 2min timer and not the quadpacer control, but I don't miss it. As set of alkaline batteries lasts me for a month or more, while 2300mah NiMH AA's last 1-2 weeks between charges.

Maintenance -- The skreechy complaints from previous reviewers about the battery compartment leaking water and destroying batteries are nonsense. Let's get real here: the 3000 is not the same design as the sealed-cell Sonicare units, and the fact that it has electrical contacts in an open-able compartment is not a design flaw (as some have declared). In fact, I find this unit to be quite well-designed and simple, but it does need a little bit of care. Anyone who has used an underwater camera case or gone diving already knows how to take care of water gaskets, but for the uninitiated: Dry gaskets do not provide a perfect seal on *any* product. In order to seal out water, the battery compartment gasket needs to be prepared before the first use, by swabbing a little bit of Vaseline or similar on all sides of the gasket surface. This will eventually degrade the gasket (lithium grease would be more appropriate), but it's worked fine for more than a year on this last one. If I were hostile, I would take away a star because Philips/Sonicare should provide a small packet of gasket grease in the box, but other than that, it works perfectly after lots and lots of use.

Great item!
After thinking about buying one of these to replace my normal toothbrush I bit at this one because of its lower price. There really is a noticeable difference! My teeth feel smoother and cleaner after brushing than with my old brush.

I have not had any problems with water intrusion, but I've been careful about not soaking the thing. I've also only had it about a month.

Overall I'm very happy with the product and would buy it again.
