    These last roughly a year. So don't throw away the receipt, and when time comes, claim a replacement under warranty.

    • how so?

      • We had this model, both brushes lasted a year and broke down within a month of each other. Then we got a set of replacement brushes, which also lasted a year, also broke down within a month of each other.
        Now we're using the 9900 series. One brush broke down within a few months, was replaced. But the other one is close to 2 years, fingers crossed.

    Just a heads up for anyone looking to get one of these for the first time, I'm a big fan of the toothbrush but the replacement heads are very hard to come by at a reasonable price. If there is someone out there who knows how to get them at a good price, please let me know!

    • Shouldn't be an issue for aftermarket options via eBay, Amazon, AliExprees etc. I was able to get cheap alternatives yrs ago when I owned one, now I use an Oclean variant due to it being a cheaper option. The Phillips failed (like most) where the head connects, the rubber/plastic surround will eventual break & let water/crud in, damaging the internals.

      I usually get the heads from the Shaver Shop when they are on special, got a couple of these last December for $48 per pack. Not super cheap, but best I've been able to find.
      I've tried the aftermarket ones before and they felt terrible in comparison.

    For this price I’d rather not get it.
    I have a Oclean version and it’s great

    • +1 for the Oclean

    I had three Philips Sonicare products over the years, they barley last a year, sure they replace them under warranty but not worth it in the long run,

      Also Oral B technology is much better than sonicare from my experience

      • I went back to using a standard tooth brush, much cheaper in the long run,

    • Same with me, guaranteed to break

    • +1

      Odd, my one has lasted about 4 years now and still going strong. Battery holds a charge for approx 2weeks too

    • +1

      I got 2 over 9 years ago, one died after about 5 years, the other is still going fine, and the replacement for the first is also still going great 4+ years later.

    • Yes no need for it but I guess people like spending more to be unique or fancy. Just have a look at the dual handle bundles for oral b (i have the genius 8000), the Go on sale sometimes for much cheaper than $400. Even the Smart models or pro300 is fine and can get the genuine crystal brush heads much cheaper and easily. Oral-B have a patent over their brush heads which is why the Phillips ones look funny.

    Using my first Philips Sonicare for at least 3 years now, so far so good. Even the battery lasts over 2 weeks with twice a day brush of 3 mins. Will never go back to Oral B. Quality replacement heads at a reasonable price is the main issue for me.

    • I will never buy another Oral-B. The last two I've bought I have to charge more than twice as long for half the runtime - I am not exaggerating - of the cheap Soocas toothbrushes I had before them. Did I get two duds in a row? Doesn't matter.

  • +1

    Serious question….. why would I buy these at over $300? Never having used one so no idea. How do they compare to the 'always on half price' specials for $20-$30 electric toothbrushes from Oral B etc? Considering I could buy a fair few of them before meeting this cost

      I have not had any issues with my teeth and gums since moving to Sonicare (mid range model) from Oral B. Buy a cheaper base model. The functionality is the same but lacking in features, that's my understanding of how they work. Happy to be corrected.

      A few friends who are dentists don’t recommend Sonicare since it’s expensive (head refills and the unit itself) and that the sonic movement isn’t as effective as a traditional physical brushing type like you get on an electric Oral B. Most of them recommend the base level Oral B one with the pressure sensor which you can get for $70-90. I got it from Woolworths in a sale for $50.

      • Oral B gives something to the dentist clinic as far as I am aware, clinic promotes Oral B products rather than Philip’s.

        • Marketing?

          • @wangsk: Free Oral B toothpaste from local dentist. Small one, not the usual size in the supermarket.

        • Yep, aware of that, hence why I mentioned they’re friends and didn’t have an ulterior motive to sell me Oral B products directly.

          They regarded the sonic motion effectiveness as not being as effective as marketing claims it to be.
