DerffinReplacement Brush Heads, Compatible with Philips Sonicare Electric Toothbrushes, Classic Toothbrush Heads HX6014, Fit The Models of HX3/HX6/HX9/HX8/HX7 Series (8 Pack in White)

These are a great alternative to the ones supplied by Phillips. They fit perfectly and last the three months I expect of them. They come at a great price and I would definitely recommend them.

These work and are much more affordable than the normal ones, just a bit of a struggle to get on but a good substitute. I have the sonicare 3100 and it works!

Recommended, they fit well and firm, to begin with they did feel quite hard against my teeth which felt strange HOWEVER this is purely because I hadn't replaced my previous toothbrush head for the suggest time which apparently is every 2 to 3 months.

Compatible with Sonicare 3100. Really great quality and feels no different to the original, excellent cleaning and no issues with noise or unwanted vibration. Bristles feel good quality and firmness/length no different to originals.

I’ve been using the Derffin replacement brush heads for a few months now with my Philips Sonicare toothbrush, and overall, they’ve been a decent alternative to the original heads. They’re compatible with my handle (HX6014 model) and fit securely without any issues. The bristles feel firm but not too harsh, and they clean well, leaving my teeth feeling smooth and fresh after each use.In terms of performance, they do a good job for daily brushing. They’re not quite on par with the genuine Philips heads when it comes to quality and longevity—after a few weeks, the bristles start to fray slightly, and I’ve noticed they wear out a bit quicker. That said, considering the lower price point, they’re still good value, especially if you’re replacing heads frequently.They don’t have the brush head replacement reminder feature that some original Sonicare heads do, which could be a downside for some users. However, if you keep track of your replacements manually, this isn’t a major issue.Overall, I’d say the Derffin brush heads are a cost-effective alternative for everyday use. They may not last as long as the originals, but they offer solid cleaning performance at a fraction of the price.

Good replacement toothbrush good fit.

I purchased these for my Phillips toothbrush as I just can’t justify paying out for the branded. These do the job just as well and you get so many for the value of money! They’re just as good quality as the OG and fit perfectly on my toothbrush. I don’t think I’ll ever not buy these
