It works for sure. Price is great! Use in winter outdoor activities. Bluetooth connection easy. However, button is near pocket. Either with bending over or going into my jacket pocket, I have numerous times accidentally changed the setting or turned off. You don't know until you are either cold or hot. I think button on shoulder area may work better or have a lock out with the bluetooth app that disables button. I would not buy this again because of this.

Vest is nice untill you pullout the dollar store wire that supplies the whole vest's power. FAIL. Next time instead of cutting the cost for quality nix the Bluetooth feature instead.

5 stars! Purchased as a gift for our son-in-law. He loved it. We think this is the best present we have ever given him.

Works great! Easy set up. Easy to use. Comfortable and warm.

I recieved my new vest I fully charged the battery and it works great. Just like my Moble Warming socks synced vest to my phone it works wonderful. I would recommend to everyone.

This vest is perfect for outdoors and indoors. It needs to be snug in order to feel the heat, but it adds warmth to the core when having to be outside in cold temperatures. It is lightweight and fits nicely under a parka. On those colder days and evenings, it is nice to wear indoors on low heat. This is the second one I have purchased - the first for my 96 year old father and now for my husband. (I had received one for Christmas one year and wear it all the time when I ski and during school recess duty.) I highly recommend it!

My new warm buddy is great
