My previous attempts are all failed. I've been trying to make everything better and start all over again. I'll explain my framework and do some surveys about a few details. Please give me as much criticism as you can. I will be grateful.
Currently there is no perfect product, but I found a few relatively usable products available among manufacturers. I’m planning on design my own device after scaling up, which is not realistic for now. So I’m going to start with a kind of neck fan with a cooling plate at the rear section. It will fully operate about 2 hours and much longer if you turn off the cooling plate. I’ve tested it the whole summer. It’s not as efficient as AC, but definitely was usable in hot weathers and kept me from fainting.
This is my competitor's product. I can get the same device and print my own brand and even pattern it. Please comment how do you like it. Thanks.



The first part: Business Idea
Cooling Neck Fan
I noticed an increasing need on personal cooling device. Google Trend shows more than 30% peak search increase each year in North America and European countries. Since temperatures are getting higher and higher every summer.Currently there is no perfect product, but I found a few relatively usable products available among manufacturers.

The only hiccup is, the need is seasonal. Obviously nobody need it in winter. So I did another research and found out a lot of people, females especially, are experiencing cold hands and feet in winter. Rechargeable warming mittens and socks would solve their problems. But such things are not widely accepted in the US and Europe. I'm not sure how big the market will be. Please comment your thoughts about these warming devices. Fingerless warming mittens, warming socks, warming bag(real bag with space for accessaries)


Competitors are selling
My competitors are selling phone cases and it seems pretty profitable. But there are already more than a million sellers all over the world selling phone cases. And honestly, I can't do any better or sell anything special in this area. So should I also sell phone cases?
