I hate summer, so I was trying to find an item to survive this year's heatwave, and first purchased a popular neck fan that costs several thousand yen. It felt good enough to be cold at the current temperature, but I had a feeling that in a heatwave, hot air would blow around my face. So I bought this expensive neck cooler that I had been interested in to see how good it was. As a result, the cooling on the inside is excellent and it can cool the neck area quite a bit, and it is very convenient to be able to control the air volume and level from hot to cold with the app. I think it's worthy of being called a cooler, and I'm looking forward to seeing how useful it will be in the heatwave. I immediately ordered more for my family.
