OralClass Replacement Toothbrush Heads for Philips Sonicare Click-on Handles, Medium Soft Electric Brush Heads Refills, 8 Pack

Switching to these replacement brush heads has been an absolute game-changer for my morning routine. The precision-engineered bristles strike the perfect balance between being tough on plaque and incredibly gentle on my gums, leaving my mouth feeling "dentist-clean" every single day. I was particularly impressed by the contoured design, which effortlessly navigates those tricky-to-reach spots behind my molars that my old manual brush always seemed to miss. They snap onto the base with a satisfying, secure click and show zero signs of fraying even after weeks of vigorous use. If you’re looking to elevate your oral hygiene without overcomplicating things, these heads are a small investment that yields a noticeably brighter, smoother smile.

These fit my electric toothbrush perfectly for a fraction of the cost.

The replacement toothbrushes work well with my sonic toothbrush. They last a good while and do a good job cleaning my teeth

The cost of original replacement heads is absolutely insane for this toothbrush (Sonicare 4100). I got a great deal on the toothbrush before Christmas, but it only came with one head. I saw some reviews of off-brand replacement heads in the New York Times and their main complaint was the off-brands seemed to use stiffer bristles. I picked these out because they claimed to be soft to medium. I got this 8-pack for less than the cost of 2 brand name replacement heads. The recommendation is to change the brush every 3 months. After 3 months of use the head and bristles still showed minimal wear (if they wear out faster, you may be using too much pressure), but I replaced it on schedule anyway because the inside gets a little moldy (I have started to remove the head between uses so the inside has a better chance to dry out and prevent mold). That means I have a 2 year supply of heads, which is great. These heads are not identical to the original C2 head. The brushing surface is a little longer, but not as contoured (the original seems to get to the back of the back teeth better) and the clusters of bristles are not quite as dense as the original. They are probably a little softer, but not by much, which is fine. I have switched back and forth with the original some to compare and there is very little difference. The fit is tight and they do not snap into place, but it works. You are supposed to leave a small gap at the base so it can move.

Very functional brushes. Fit power unit perfectly and brushes have the correct bristle strength to clean very well.

These replacement brushes are just great with my electric toothbrush. Why pay more for the name brand when you can buy these and they are just as good. Highly recommend! Great price point!

Maybe it's just me but They feel like they don't fit correctly. Also the pics show that there are covers on the toothbrushes ( which is why I bought them. I was going on a trip and had misplaced the cap/ covers,I needed new heads anyways so these said they would come 1 day ( they came 4 days) . I have used generic heads before and I couldn't tell the difference, but these are a smaller brushhead, don't fit snuggly and feel like they will fall off, More than half already had changed color, I can only assume from sitting in a warehouse as the pack was very dusty,

So apparently it had been awhile since buying Phillips replacement heads for our SoniCare toothbrushes (honestly, I think the last time was Costco where the expensive price was probably overshadowed by the rest of the stuff in the cart), but I had sticker shock when I saw the current going rate of the Phillips brand. Naturally that spurred some research on Amazon for a less expensive option. I gave these a shot, not 100% sure how they'd measure up against the Phillips brand, but I was pleasantly surprised at the fit and quality, and even more thrilled because of the way more paletteable price range. They don't fit as perfectly as the Phillips brand ones, but they do fit and work fine. The first time switching to these, I did notice they vibrate a little more vigorously (probably because it's not as perfectly fit), but once you get used to it, it's totally fine and seemingly better. I feel like between the slight difference in the brush shape and the fact that it vibrates more vigorously, it actually cleans better than the Phillips brand heads, at least it feels that way. I'll definitely be reordering these from now on!
