I was speaking personally for myself. $40 more isn't really that much in the grand scheme of things but when it comes to your health/teeth, it will save you much more in the long run, so worth the investment IMO.
Eh, unless you have some sort of evidence to support the idea that buying a more expensive toothbrush will "save you much more in the long run", it's really just that you feel better using a a more expensive toothbrush. And that's fine, but let's not pretend that paying more = better.

A google search will show you that the higher price brush (with a MUCH stronger motor) is better at cleaning and removing plague than the cheaper lower end brush with the weak motor that hardly cleans. You might as well use a manual brush. Now if we're talking about a $50 sonicare vs a $100 sonicare with all the whistles/different brushing modes and bluetooth, etc., I would still stick with the $50 as paying $50 more for those extra "cleaning" modes makes no difference. I just need a basic, simple and strong brush with a strong motor.

But between the $10 (Onlyone) vs the $50 (Sonicare) there's a clear distinct difference in the motor performance. Paying more = better isn't always true but in this case, it is. But whatever works for you. Like I said before, this $10 one is good for kids because their teeth are more sensitive and it's easier for them to brush and probably does a better job than if they were to manually brush themselves. As for adults (myself personally), the $50 cleans much better.

Sad part is you kind of can. The sonicare 4100's and below are now so weak they are probably comparable to this onlyone toothbrush and they retail for between 40 and 50. I would get this over that since it may be weak but it's 9 dollars so who cares

I rather get a oral b clone than this type. It's way easier to find brush heads for them too.

My black one arrived today. It came with a thin walled plastic travel case with two plastic prongs in it broken. The travel case still functions, and I don't plan to travel with it much.

A quick Google search shows me nothing of the sort, but it's certainly very easy for you to claim as much. The burden is on you to provide evidence as you should well know that I can't prove a negative.

Your claim that "you might as well use a manual brush" is ridiculous, as the fact is that (with some caveats explored below) there is a statistically significant improvement in oral hygiene when using an electric toothbrush: https://pmc.ncbi.nlm.nih.gov/arti...MC3652371/

You don't appear very interested in facts, but should you care to read it you will note that they use an Oral B Vitality Dual Clean electric brush, which is an oscillating-rotating toothbrush rather than sonic. If you're interested in more facts, sonic toothbrushes are actually inferior to oscillating-rotating brushes. Here is one of many studies proving this to be true (even if you don't bother to read it, at least bother to scroll down and see the many studies showing this to be the case): https://pubmed.ncbi.nlm.nih.gov/24282870/

As you noted, the greatest difference in electric (including sonic) vs manual is shown in children because their general lesser fine motor control and inability/unwillingness to brush for the recommended 2 minutes is more significantly impacted by the use of an electric toothbrush with timer: https://www.wjoud.com/abstractArt...J/fullText

What you don't seem to acknowledge, though, is that a more expensive toothbrush is not inherently better than manual brushing if your technique is flawed. What applies to children - though for them there is a more physical component - also applies to adults. Virtually any toothbrush can be extremely effective as long as you're doing it right.

Feel free to justify spending 5-10x as much, I don't care. You are entitled to your opinions, of course. Personally - having used a variety of "nice" oscillating-rotating electric toothbrushes in the past - I like this particular sonic toothbrush because it and the replacement brushes are extremely cheap. I do a better job brushing than with OR or manual toothbrushes because it doesn't feel quite as much like a chore and the cheapness of the brush heads means I'm likely to replace them more frequently. These are what are likely to improve my own personal dental hygiene and almost certainly has a greater impact on oral health than "motor performance" (whatever that means).

Maybe I'm wrong, though. Please come back with solid evidence - not opinions, not some blog post by a dentist, etc - that a name-brand body (not the bristles themselves, as that's a different discussion and not part of your claim) is better in a statistically significant way over a generic or knock-off, and I will concede and apologize for doubting you.

You can though, especially when the toothbrush itself is essentially a knockoff of the name brand you're comparing it to. Knowing whether it's so cheap because it's a 'generic' brand or because it's an inferior brush seems pretty important and this is one of those devices where you're spreading out the cost over several years so a 20% improvement could easily justify spending $10/year on the better toothbrush.

I had nice a few nice Sonicare brushes that were built like a tank and the battery lasted forever. They finally died and I replaced them with another Sonicare (don't remember which model) that was not impressive. Switched to Oral B iO series (the dual set) from Costco and it was amazing. I've had 2 sets either quit working all together or the power of vibration nerfs. Great brushes when they work but IMO totally not worth replacing every year or so.

Got one of these and they are hands down worth the $9 or even $28. I think I paid $16. They are not as powerful as a Sonicare or Oral B but on the highest setting (Whitening level 3) they do a good job of cleaning.

The studies you linked don't actually address the question we're debating. They compare electric vs. manual and oscillating vs. sonic, not a generic $10 sonic toothbrush versus a Philips Sonicare. My point wasn't that every expensive toothbrush is automatically better. It's that reputable brands like Sonicare generally have better engineering, quality control, and a stronger track record than ultra-cheap generics.

I'm not aware of any head-to-head clinical studies comparing Onlyone to Sonicare. What I do know is that Philips has invested heavily in research and validation of its products, whereas I haven't seen comparable evidence from Onlyone. For that reason, I personally trust Philips more. While I can't prove how well Sonicare performs compare to Onlyone, it is my personal opinion that it feels cleaner to me. If you prefer Onlyone, that's fine. You value the lower price, and I value buying from a brand with a stronger track record. I think that's really where we differ, and I'm good leaving it at that.
