There are way too many alternatives out now to pay this much for brush replacements!

100%. I used to have the sonicare and then I bought a copy brand on Amazon. Literally does the same thing! Same quality. All it is is a brand name hype with expensive refills.

I've tried a few generic alternatives from Amazon, but in my experience, they haven't matched the quality of Philips' newer options like the C3. The recent upgrades from Philips are noticeably better, and the no-name brands just don't perform as well for me.
If anyone has found a reliable alternative comparable to the C3, I'd appreciate the recommendation. I've already tested brands like Tiosdurfego and Cavznu on Amazon, and they were nowhere close to the original in terms of quality. For now, I'm sticking with the original C3 until I come across a good generic option.

Curious if anyone has actually found a generic that's consistently as good as the C3s.

So what are some good third party brush head replacements that you or others have tried?

Costco had the highest end version of these on clearance once for $9.97. I bought like 8. I guess we have brushes for life now

I remember the days where the 10 pack would go on sale for like $40. Then all went to shit with the economy and they bumped the prices up to $60 and on sale at $50. Now they don't even sell the 10 pack anymore. It's infuriating how insane the price gauging is and there's no end in sight. Prices will never, ever go down. This is the new norm.

I have used the multiple generic ones and genuine ones over the years and while they're slightly different in firmness and longevity (albeit none of the generic ones have failed in 3-4 months), they all get the job done pretty well. No cavities in the past 15 years. Its not a night and day difference to warrant the insane markup that genuine Phillips charges.
