I didn't' realize it didn't have the mister - thanks!
welcome!
yeah the boxes that say 3-1 have the mister plus a few of those plastic wips or whatever that go with using the mister. but then it doesn't have the accessory clip or the body strap, which shark overprices both at about $24.99 ea.

I ordered this and also the one from Ulta to see if the one with the mister is really better. I found a coupon on Ulta for 20% off the 3 in 1 model - will probably post it.

How does this compare in cooling performance to the many no-name alternatives found on AliExp/Amazon? Like the no-name models, this uses a drone motor with a peltier plate in front of it, so the 15 degree cooling claim seems dubious. I'll admit the attachments are interesting, but nothing that can't be improvised. The form factor also throws me, as it's far less compact than most other designs.
From the reviews I've seen it's not worth it. To use the fan you must use the fan attachment. To use the cooling plate you must remove the fan. To use the mist (not this model) you must sacrifice both functions and misting lasts for about 10minutes. Seems very overpriced and a hassle to carry around the attachments.

Wait... so the fan is at the front of the housing instead of the back?
Does that mean the cooling plate has a completely separate fan built in, since it won't work without one? (Peltier plates work on hot-cold differential and require cooling the hot side to drop the temp on the cool side)
If so, that seems needlessly complicated.
I bought this for $15 and it doubles as a backup battery. Only downside is the crappy 3D printed plastic: https://a.co/d/0jj7Iogd

This thing is interesting, but I think the peltier plate will have a fan blowing out the other way because it is basically a heat pump where it need to dissipate the heat somewhere else or else it will just start to heat up...

No, it blows directly at the hot side to cool it.
The fact that it's blowing in the same direction as the cold side is not a factor, because you're supposed to make skin contact with the cold side and (hopefully) the ambient temp isn't over boiling temp.
A lot of thermal dynamics problems with real world applications make zero sense on paper if you stick to textbook definitions and classes.

Ah, I guess that's another way to do it... I made a "phone cooler" like 10 years ago with a peltier plate and stick a samll cpu fan with the copper heat sink and it blow air the same way. It's find to use it that way but it depends on where you put that thing, if it's like one of the picture where you put it on your neck I'm not sure I like warm air blowing close to the other area of the body...

That's where thermal (also, fluid) dynamics comes into play.
The thermal coefficient between ambient air and skin temp changes enough to feel cool. And you also have a circulatory system piping cooler temps away from the targeted area slightly, so it's not a closed system.
But if you're thinking of will cool without direct contact, it will not.

Our community has rated this post as helpful. If you agree, why not thank kabukicho
the downside is this costco kit dont have the mist adapter which the regular channels include
