5pc Toothbrush Heads Compatible with Fairywill D7/D8/FW507/508, 551/917/959/D1/D3 (Black)

Good product will buy again!

These brush heads fit my electric brush perfectly and seems to do the job well. They were not too hard or soft, had the auto-change feature to let you know it may be time to replace, and came in individually wrapped packaging to keep them clean until needed. I never had an issue with bristles coming out or causing any damage to my mouth. If these fit your model of brush, I'd recommend getting them.

These replacement brush heads fit my electric toothbrush perfectly and were very easy to install. The bristles feel soft but still clean my teeth really well without being too harsh on my gums. I like that the pack comes with multiple heads, making it a great value for the price. They work just as expected, and I would definitely purchase them again.

perfect replacement heads for toothbrush, and sturdy

Super quick arrival, not wasteful in packaging just a small box holding the 5 tooth brush heads, affordable. Will buy again!

I received the replacement brush heads quickly and they were packaged in a sanitary and sturdy manner. The brush heads fit perfectly. the bristles seem to be about the same stiffness as the original ones - a bit stiffer than a soft bristle, but not as stiff as a medium. The brush head seems a bit smaller than the original, but that may be my perception or they may be a little more narrow. Regardless, the brush is better than the original to get into more awkward and smaller areas. I would rate performance at least equal and likely better than the original part. I will continue to use this brand of replacement brush and this vendor in the future.

I've used multiple kinds of toothbrush heads ranging from official oral-b to other third party heads. So far these heads have been the best third party head,they claim to be food safe and have DuPont filaments which no other third party head does. I can't verify their claims myself of the materials,however by feel the bristles are high quality and I can believe they use DuPont materials when I compare them to my previous heads.They;re decently firm but not hard,and significantly softer than the other third party heads I've used which verged on hard The parts other than the bristles feel well made as well,so far I've found this to be the best value for your money in the oral-b toothbrush head. The heads feel just as good as the oral-b heads and as effective while being significantly cheaper

I think they are totally worth a try. they are like the other name brand brush heads where you just need to screw it on your handle and that is, they are fitting perfectly on the handle and they are staying tight when i turn on my toothbrush. I think the bristles are fine. They won't be too soft or hard so i think they will fit my gum very well. Vibration is good enough for cleaning and they are not making too much noise on my handle. Overall i like how they present and the result as well.

Son compatibles con casi todos los cepillaos!! Tienen mucha calidad.

硬めで非常に良いと思う。

Habe die Ersatzbürsten schon mehrfach bestellt, sind qualitätsmäßig gut und passen perfekt auf die Zahnbürste. Sind qualitätsmäßig gut und passen perfekt
