This seems like generally good tech, but kind of a crazy price? ($800 AUD for me to buy locally)
Resolves YES/NO 3 months after purchasing the toothbrush
Resolves N/A if I do not purchase it
It only really needs to save you that much in time, or one major dental cost throughout your life to payoff, is that likely? Would I regret the purchase?
Product page (AU link), "Brush. Floss. Rinse. In just 3 minutes"
Update 2026-09-04 (PST) (AI summary of creator comment): - If purchased on sale, regret will be evaluated based on the original price of $500 USD / $800 AUD.
1,000so you can share 1 unit by switching the heads, and there is a refill dock thing which refills the reservoir, so you really only have to refill the unit similarly to a regular water flosser.
I think there is a very high chance that I will actually buy this if for no other reason but to not waste this market, so I might be coping about the 'upsides'..
@Gen Manifold Rationalism: They tell me I'm going to regret it in 2 out of 3 chances, so I HAVE to buy it.
@Eliza When the auditor asks how I justify claiming this on my tax, I will point to this market: I bought it even though it was clearly a mistake, for marketing purposes!
@Eliza how many traders do you think we need for me to actually be able to claim it as a deduction tho
@Gen Are there studies that determine how many traders a Manifold market needs before it's calibrated?
Against my better judgement I finally watched the video, which just confirmed what I expected....
The 3 month timeframe is possibly too soon to get a true answer, 1 year would be better and I think there should be a separate 1 year market if you do buy it.
Participants who take the No side are HIGHLY encouraged to write comments here so they can follow up with loads and loads of "I told you so" later on, which can help instill and build the sensation of regret.
I guess I'm thinking something like:
It's going to be time consuming or annoying in some way that reduces total usage.
Eventually you will just go back to the normal toothbrush most of the time.
This looks like V1 of an expensive tech gadget. Here are two common pathways for V1 of an expensive tech gadget:
A.) There is never a V2. It wasn't very good. Didn't work well. Had some critical flaw that no one could fix.
B.) There is a V2 after a year or two because it had promise but V1 missed the mark in numerous annoying ways. V1 becomes very very very obviously a dead product and V2 is so much more desirable that you just absolutely need to upgrade and you're upset you spent six months' wages on the V1.
How often do you brush?
Daily, sometimes twice daily, sometimes not daily, it mostly depends on my sleep schedule and when I'm travelling. If my sleep is bad, I'm skipping days, if everything is good then daily.
How often do you floss/use the water flosser?
I haven't used the water flosser in at least 3 months, prior to that it was ~weekly? I started using the little plastic pick things again bc I can leave them in more convenient places than in front of the sink, which is not a place I want to spend much time. I see one major benefit to this brush being the 2-in-1 efficiency
Do you buy tech doodads often?
Idk if something seems useful I will buy it, but I don't buy stuff just because it's new tech
How often do you regret purchases like this, such as kitchen gadget or combo tool?
It is pretty rare that I regret buying things as I often put off making purchases until they are obviously worth buying.
I upgraded my laptop recently for the first time in 9 years, and I'm upgrading my phone to the new iPhone this year (currently iPhone 13 pro max 256gb; I need bigger storage). It is pretty typical for me to buy a top tier product and then use it for a long time before upgrading.
Regret is usually measured quite quickly bc I will just refund it. We have good consumer laws in Australia, and refunding an item that does not meet expectations is trivial. If the toothbrush sucks I would return for a full refund within a month, most likely
this will plausibly save you time/increase the frequency you've "flossed"?
Yes if it works as described flawlessly then it would meaningfully improve my dental hygiene. I have good dental genetics (or w/e) and have never had any issues exceeding a tiny filling. Usually go to the dentist once a year.
Wtf is that toothbrush lmao
@JasonMendoza2008 ok I saw the ad, this is clearly a good product, if you regret it I bet you’ll regret regretting it
@Gen totally insane.
"here mom, have a toothbrush that has 10,000 ways of breaking, won't save you any more time than flossing and brushing normally, and will only cost you the price of a new filling every month or two when you replace its specialized head. and no, you probably can't use it anyway if it needs replacing, it's AI powered 'smart tech'!"
@Stralor devil's advocate counterargument: Dyson makes really good tech. Powerful and reliable.
(prob still not worth)
@Stralor if it were me deciding whether to bother, I'd require an expensive AI powered toothbrush to:
clean my teeth with little to no input from me
guarantee no cavities
repair enamel
fix unevenness in bite and aesthetics
and give me moviestar pearly whites
... not just use its AI brain to stare at my gums while I do the work I usually do just with occasional added jisms of water from a tiny reservoir.
like seriously, it has to compete with what a roll of glide and a 99¢ stick of plastic can do in a mere 5 minutes across two sessions a day. so it better be goddamn magical
@Stralor idk I already have an electric toothbrush and a water flosser thing, they are separately ~$100 each. I could see making the leap if it’s actually good.
Your comment about the reservoir is a good point tho lol.
@Gen Most people's willingness to pay for this does not reach $500. If the recipient does not value this at at least $500, then you are deleting surplus value from the world.
@Primer Granted, I am discounting the monetary value of the joy of both giving and receiving the gift. Those are also variables to factor into the equation.
