Onlyone is ok, best suited for kids, but my teeth didn't feel very clean after brushing since I barely felt anything even on the hardest mode.
Community Reviews
This cheap sonic toothbrush stands out for its low price, eight brush heads, and surprisingly solid cleaning for the money, especially for anyone coming from a manual or basic rotary brush. The heads are reported to last a long time, replacement heads may work with Sonicare handles, and the included travel case adds a little extra value. The main drawbacks are a weak motor for some, very soft stock bristles, and a body that rolls on the counter without a stop nub. It feels like a budget pick that can work well if you are fine with its compromises.
Common Questions (5)
It is reported to be weaker than Sonicare and Oral-B models, with some saying the motor feels very weak and the brushing feels soft even on the highest setting. Others find it strong enough for the price, especially coming from a manual brush or cheap rotary brush.
The handle can roll because it lacks a nub or flat stop. A simple fix is to add a small glued-on bump, such as a piece of plastic, wood, or a cabinet-door stopper, and some people just stand it upright.
For many shoppers it is considered a strong value at $9 because it includes a handle plus 8 heads and is still better than a manual brush. The main caveat is that it may not match the cleaning power of a higher-end Sonicare or Oral-B.
The heads are reported to work with Sonicare handles, and Sonicare heads and charger can also work with this toothbrush. That makes the deal more attractive if you want cheap replacement heads or already own Sonicare accessories.
The included travel case is a thin plastic case, and one report says two internal prongs arrived broken. It still functions, but it does not seem especially rugged for frequent travel.

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.

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.ni
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
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.
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.

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.
