It works and recommended

I can feel the difference with this hoodie on. Often I'm working at home and notice I'm feeling stressed or anxious. If I put the hoodie on I feel almost immediate relief. My body likes it and I often forget to take it off until it's time for bed. Even then, sometimes I sleep with it on. It helps tremendously. Make sure to pull it down in the back and cover the base of your neck. I bought one for my sister and also for my mother, I highly recommend it.

I put my iphone 12 in side the Hat, the wifi still works wellThis Hat is a product of Halsa from Amazon America so I think it is reliable . But it is useless to me.If I can not return, Any one in Singapore can contact me to get it for free (do not have to waste money (62 USD) like me)

It does not work at all. I put a phone playing internet music in it and wrapped a couple round. The phone still playing (getting signal). I fold it into several layers and wrap the phone, still able to call it. Waste of my money. If possible I'd give no star.

It really as silver in it!

I used my EMF tester on this, and it reduced reading a bit. Since you need a whole for your face it won't reduce the reading completely down to safe level. Albeit I do like the comfortable fit, cozy around the neck, and fact that I can easily bring it with me to use if I am to work elsewhere.
