      Yup. As long as it does not have a screw base.

    • Has anyone tried the Adaptive Clean heads? Are they really that much better than diamond?

      I prefer the Adaptive Clean. It seems to contour the tooth surfaces better, so I feel it seems to clean between and around the teeth better. The main advantage of diamondclean is whitening which I don't really care about. At some point Costo switched to the DiamondClean packs years ago, and I was pretty disappointed with the Diamond brush heads. It's preference, but if Costco sold both I would choose the other type.

    • Any good aftermarket alternatives? I know there are cheap ones from Ali/ebay but I'm unsure how safe those are. (Ie: what are they using for the nylon bristles)

    • I just got my DiamondClean toothbrush from the Prime Deal and it comes with three heads, so I'm going to give them all a try to compare them back to back.

      The other interesting thing is that the DiamondClean brush feels a bit different than the Series 3 brush we are also using. I can't pin it down, but the oscillations feels a bit stronger in the normal cleaning mode. I thought all of the Sonicare brushes are exactly the same cleaning action except for features.

      I thought I was imagining things, but If I look at the brush while the brush is working...... I think the brush head on the Diamondcare handle oscillates back and forth at a slightly wider arc than the 3 series. I wonder if there is some way to prove or disprove this theory. Maybe I need to figure out a way to take a picture of the brush and measure how much the brush oscillates.

      I got another pack a couple of weeks ago too. You can get your money back if you can endure the line up or go at a non peak time

      To add to the anecdote...I find that when I am replacing my brush (Flexcare Platinum), the new brush is always "stronger" in its vibrations compared to the old one. Not sure if this is due to wear on the motor or battery degradation but I notice what you're describing even within the same model...

      Ask yourself if you really want to be the guy who bought a >$100 brush and is now trying to save a few dollars on replacement heads?
      Nobody can guarantee those cheap clones and when brushing is something you do multiple times a day is it really worth the gamble? Yeah I get the fact they're all probably made in the same factory in China but at least with the official heads there's probably some real QC going on

      good point too. Both my handles are new. The 3 series was bought 3 weeks ago. I had a Flexcare that was like 7 years old and even it felt stronger than the new 3 series. Maybe the 3 series specifically is weaker.

    • I buy the E-Cron® replacement heads from Amazon. Drastically cheaper. The 'official' heads are almost comically marked up for a simple piece of plastic - classic razor and blades business strategy. Side by side and when used I can't really tell the difference. A little softer bristles but seems to work just as well. Would I feel better about having OEM product - sure - but given the price discrepancy, meh.

      The Flexcare is one of the best models they ever have produced IMO, in terms of both durability and overall quality, which is much more than I can say for the actual Diamondclean handle itself.

      These have worked surprisingly well for me -- durable and clean well. I was skeptical at first of course, but have re-ordered multiple times over the years. 4 for $1.80.
