PhilipsSonicare Original C3 Premium Plaque Defence Standard Sonic Toothbrush Heads - 4 Pack in Black (Model HX9044/33) (Packing May Vary)

I found very little difference between the original head that shipped with my Sonicare 9000. I have little concern that these are not a genuine replacement at a reasonable price point. I found the bristles medium-to-firm and provide a great and thorough clean. My toothbrush continues to alert me automatically when the head should be replaced (usually between 11-14 weeks). You can ignore this recommendation and get another few weeks out of the brush head. They fit the handle perfectly.

Genuine which is a relief. They're much firmer in my opinion than they used to be so I find they're more aggressive when brushing. They're a great size as they fit all areas of the mouth, some brush heads are larger and don't, I imagine it depends on each personal preference. These are my favourite, but I wish they weren't so firm.

Overall I'm really happy with them. The design is sleek and the bristles are soft on my gums.However, I do think they're a bit overpriced for what you get. A single head lasts around 2-3 months. But if you can afford it, these toothbrush heads are definitely worth the investment."

Strong, effective heads - pleased with my purchase

😊 Pleased to say these are the real McCoy, I ordered these 4 pack of C3's from Amazon themselves to ensure they were genuine Phillips replacement brush heads, actually came from Amazon EU as Amazon UK were out of stock at the time. I have them on Subscribe and Save, so had them a little cheaper than by buying one off, you can cancel, miss or extend the next scheduled shipment in settings.Genuine Philips C3 brush heads and every bit as good as the exact ones that came with my DiamondClean 9000. I made the mistake of buying some cheap third-party brush heads on a well known auction site - they were rubbish, lost loads of bristles and were softer with smaller heads, had 6 but each one wore out in a month. My teeth did not feel as clean either.Only on my 2nd head from the 4 pack, but the genuine Philips ones last a full 3 months and even longer if you ignore the warning indicator light to replace the brush head, mine flashed up on the brush handle, but when i examined the bristles closely, they were still in good straight condition and cleaned my teeth well, i got another 3 or so weeks before i decided to swap, i reckon i could have got longer.😍No comparison really with the cheap third party ones, you get what you pay for, long lasting performance and very clean feeling teeth!I only wish Philips would make them a lot cheaper personally, after all - Philips charged me an Arm and a Leg for the DiamondClean Handle, now they charge me a Hand and a Foot for replacement brush heads, surely if they only charged £5 or so each for a brush head in 2 and 4 packs, they would sell more by volume and everyone could afford to smile with confidence, instead of resorting to not very good third party brushes!

It is a replaceable electric toothbrush head.I checked the Philips website, and it fitted ours.(there seems to be 3 sizes - but the mist common "adult" size is this one).Pricey for what it is, BUT so are just about all the other "genuine Philips" replaceable "consumables"!So, for what it is, it is reasonably priced.There is a bewildering array of variations of Philips toothbrush heads - so I just went for exactly the same as the toothbrush originally came with.I have white ones, and now these black ones are for my spouse.Same thing, but in 2 colours. Probably to match some of the toothbrush colours, but we got them so we could tell them apart. Mine are all white, and my spouses are all black. Simples.Anyway, all in all, we are very pleased.If you want proper, genuine, Philips toothbrush heads, this is a good place to get them.£30 for a pack of 4. Each is supposed to be for 3 months. So £30 for a year. Maybe not too expensive after all :-)

These were replacements, and slightly improved and better standard, which will improve my dental hygiene. As all brushes fit the same "holder" but the brush head itself is slightly different design quality so, so far I'm happy.

Very good, gives a real clean teeth feeling
