I bought one of these in 2018 on ebay for my dad, and had it shipped from japan.<p>Living in the US I had to jump through the hoop of making a fake japanese icloud account just to be able to access the app on the app store, which is how you control the device.<p>Ultimately it seemed like a really cool device but at least at the time wasn't very effective or practical for cooling down, at least in my and his experience. This was mostly just being outside, doing yard work etc in the hot summer.<p>I think buying one of the <$50 portable neck coolers on amazon are probably just as if not more effective
Or, for about twenty quid, you can get a semiconductor cooler <a href="https://shkspr.mobi/blog/2021/07/gadget-review-usb-c-powered-semiconductor-neck-cooler/" rel="nofollow">https://shkspr.mobi/blog/2021/07/gadget-review-usb-c-powered...</a><p>I have one. Rather effective at chilling my blood. No app needed.
1500 Hong Kong bucks = ~200 US dollaridoos.<p>In Japan they have tight fitting plastic shells with fans that pump air in to jacket and expels through ends of the jacket. 1<p>I imagine this is much more efficient than resistive heating clothing and allows for cooling but what about the front?<p>1 <a href="https://www.theguardian.com/world/2023/jul/25/fan-jacket-japan-innovation-keeps-workers-cool-in-heat" rel="nofollow">https://www.theguardian.com/world/2023/jul/25/fan-jacket-jap...</a>
Anyone else with hyperhidrosis having thoughts about buying one?<p>Never seen one of these before, and I'm sure people would gawk and think it's weird, but after so many years of suffering I don't think I give a shit.
Reminds me of these that instead of actually heat or cool you just make you feel warmer or colder.

I am genuinely curious about how effective these are. If I'm sweating all over my body, will putting this on my upper back help the rest of the body to cool down? Sony must have done their research so what is the principal behind this approach?
For context, the reason this exists is air con in offices in Japan are set high something like 27/28C.<p>Part of it is history, the Cool Biz campaign set the idea of 28C being the "right" temp for offices: <a href="https://en.wikipedia.org/wiki/Cool_Biz_campaign" rel="nofollow">https://en.wikipedia.org/wiki/Cool_Biz_campaign</a>
on a different note... is there a way for me in the EU to buy all this stuff sony and other vendors sell in asia?<p>possibly without customs (but i'm available to pay for it)
there are a few wrist devices like that<p><a href="https://dhamasport.com/product/cool-wristband/" rel="nofollow">https://dhamasport.com/product/cool-wristband/</a><p><a href="https://embrlabs.com/products/embr-wave-2" rel="nofollow">https://embrlabs.com/products/embr-wave-2</a><p>I was looking at them to deal with Raynauds Disease but the Sony device might be even better.
I'd really love something like this. I really suffer if I get too hot, but I just can't imagine these being effective enough to make a difference. Maybe the fact that you can feel something coldish on your skin is good placebo though.
I wonder if this is too small to be worth fitting a compressor into, or if the gains over a peltier aren't enough to consider it.<p>Regardless, I look forward to this or another device like it appearing on the techmoan channel in the coming months.
Wonder how these compare to other cooling neck metals. They cost around 3-4k hk for the good style.<p>Sony went for a different route, instead of side neck cooling, they did the back.
