Pisonicleara Replacement Toothbrush Heads(10-pc) Compatible with Philips Sonicare 4100 5100 6500 Medium Soft Electric Tooth Brush Refill Hx6920 Hx9023 1100 Plaque Control

Pro: these are off-brand brush heads but they actually stay on as the handle vibrates. Good deal and as effective as the name brand. Con: They are tight on and off. Update after 3 months’ use: these off brand brushes still fit tightly and brush bristles lasted longer than the name brand.

I was a little worried about whether the toothbrush heads would actually fit and function perfectly since they were not made by the manufacturer. They fit perfectly, and are indistinguishable from the originals. They also cost about $1 each as opposed to the exorbitant price for the manufacture's replacement toothbrush heads. Great buy, and highly recommended!

I was a little skeptical at first since these aren’t the official Philips Sonicare brush heads, but wow—these work just as well, if not better in some ways. They snap on perfectly, feel secure, and perform exactly like the original ones. The bristles are high quality and give that same deep-clean feeling, leaving your teeth smooth and fresh. I’ve been using them for weeks now and haven’t noticed any difference in performance—except for the price, which is way more affordable. You get multiple heads for what you’d usually pay for just one name-brand pack. They also come individually sealed, which makes them feel clean and professional. If you want to save money without sacrificing quality, these are a no-brainer. Definitely sticking with these from now on! You get more for a cheaper price can’t beat that. Durability: last as long as the regular ones do

Smaller than the real philips ones, but they've kept my teeth clean enough, and are way cheaper. Bristles feel fine. Would love if the bristle heads are a bit bigger.

Excellent replacement for the name brand. Way cheaper and just as good. Would reccommend.

These work perfectly w/the Sonicare toothbrush system. Save yourself the money & get these. They may not have exact fit at base but doesn't matter. The way it works is the same.

They fit my sonicare toothbrush but don’t vibrate as strongly as the original toothbrush head

These are way better than a sonicare brush heads that come with the sonicare toothbrush. Thank you so much for the amount and the value. You have a customer for life as long as the quality continues to be great with a fair price. I like that the brush heads are bigger than the sonicare brush head. When I had the sonicare brush heads, I was going to throw my sonicare toothbrush away because it hurt to brush my teeth. But, these toothbrush heads are the right size and they didn't hurt my teeth while I'm brushing. My gums are happier. I'm so glad that I didn't throw my sonicare brush base away. After looking at another lady's review and then trying this product for myself, I'm very pleased. I will continue to buy from you. Thank you for a better product.

Se adaptan muy bien a mi cepillo funcionan igual a las originales.
