This heated vest was purchased so my wife could enjoy having a heated vest this winter season. The heated vest I had previously purchased was a straight cut with multiple zippers for expanding chest width. This first thing that had drawn us to purchase this vest was the women's fit and cut. She suffers from reynauds and muscle pain so the additional heated layer under her coat provides the necessary warmth and muscle therapy needed. The vest allows you to use your own power bank for powering the heating elements so we decided to use a dual port 26500 mah bank so we could charge her phone or vest. The silicone button on the upper chest has three settings, high, medium and low designated by different colors.When using the vest as a layering, you will only need to use the blue or green temperature modes. The color and stitching is fashionable when wearing as the outer layer with a sweater. When wearing as the outer layer, the red light setting provides the highest temp when wearing the vest as the outer covering. The zipper works easily with no issues or snagging. The lighted logo on the vest not only draws only 2.1 amps from the bank, but also draws attention from other ladies at the children's school when the button is glowing red or blue!It is high quality vest but the heat is very mild and you need a power bank or to keep it plugged to have it work.The jacket is nice, but you have to order size up, it would have also been nice if it came with the battery as well, now I'm searching for battery to wear the jack smh. I should have read the small print.Good and easy to use. It fit me very much, I could ware a coat cover it too. It hide very good inside my coat. It just need a small bank power inside the pocket and keeps me warm while day.The discription and what you get is different. The vest i recieved has 5 heat settings and doesnt have heat in the front of the jacket.. not sure what coat model i got, but i was hoping for the front heat.UpdateOk, even though this jacket doesnt have the front heat, I love the material and style of this vest. Very light weight and thin. I put this under my winter jacket. I would love another one just with the heat in front for more warming.Fits me AND my husband - adjustable and not bulky. I wore this all day in Oregon and I stayed nice and toasty. The control panel on my chest made it easy to lower the heat and adjust as needed. Probably the bet money I've spent all year. No joke!I really enjoy this vest. Been wearing it both indoors and outdoors. Currently visiting a very cold area where temperature is near zero and it keeps me warm and cozy. It is easy to turn on and off. Also very comfortable to wear.Does not come with battery pack which you need to have if you wear the coat and want the heat on. I bought one but wish I knew I needed one.Se ve de buena calidad, resvala la Luisa.
