Hesubam Replacement Toothbrush Heads for Philips Sonicare ProtectiveClean 4100 Flexcare DailyClean 1100 C2, 10 Pack

I didn't like this product for two reasons. The first is that the bristles are too soft for my tastes (I like a medium hard) so I felt like my teeth were not getting clean. They felt fuzzy after a few hours. The second and annoying part of that the back of the toothbrush head has like an inset piece of plastic (so there's a seam like there is a cover placed on top of a hole). The seam in the plastic rubbed my lip in a way that it made it feel like I had a pimple on my lip if you ever had one. Didn't necessarily hurt but was super irritating. It did fit my sonic care toothbrush so if you were in a pinch, like a soft bristle toothbrush, and didn't care about the seam on it- it could be for you! It just wasn't for me in this case.

This is a good alternative to the brand name Phillip Sonic replacement toothbrushes. They fit snug and work well, each toothbrush individually wrapped for safety.

A couple of the heads worked fine. Then, they started not staying tight in the fitting; consequently, the toothbrush would not work properly. Had to hold the head to the side of the device to make it work properly. Have tried several of other non OEM heads and not had any difficulty.

Pros: leagues cheaper than the "name brand" ones, severa come in a package, works with my philips electric toothbrush just fine, quality of brushes and shape is almost the same as the name brand ones.Cons: the bristles are distinctly less firm, so if you like or need a good firm bristle on your electric toothbrush, this might not work out for you, otherwise it's fine.

I like how wide the brushes are, but after about a month I'm noticing the handle vibrates more and more. It's starting to pulse and make my hand numb as I brush. This happened with my last sonicare toothbrush after tapping it dry too much (I had to buy a whole new sonicare toothbrush set), but I have stopped that habit and now conclude it must only be the non-name brand brush heads doing it. It's ever increasing strength of vibration and noise tells me that it's nearly broken my second handle. Not good, throwing them away.

Each of these heads come individually wrapped so they stay clean until you’re ready to use them. Each also comes with a head case to keep clean between use; the bottom Of the cover is open to allow the head to dry. This fit perfectly on my sonicare and the bristles were medium soft, so they are gentle on gums.

I like that they came in an easy to open box instead of hard plastic packaging. The extras can be stored in that box. I'm using the first one now (Aug 2021). I assume they are all going to be the same super quality as this first one.

Excellent fit in my Sonicare.I always change heads every three-months and after three-months I find no obvious degradation.I plan to continue using this brand.
