How does it heat up? Mine doesn't heat up by itself at all.

I love it it make my neck warm, quality is good too

Lo retorne sentia mucho dolor al ponerlo en mi coello.

This is nothing but a thin piece of cloth with 5 magnets in it that do absolutely nothing and it does nothing to support your back or heat up your neck or find any relief. It's getting to where you have to be careful ordering off at Amazon anymore because of all these third market place sellers and their descriptions are such lies compared to what they send you and Amazon has made it a pain in the butt to return stuff if you don't live right next to the drop off places or if you don't drive so we just end up getting ripped off. Ordering more and more stuff off of Amazon because of this I won't miss my money back please don't ignore the bad reviews like I did the AI ones are the good ones in most cases now

Compact, will travel well, looking forward to using on the airplane

Great product !

The neck message doesn't heat up enough for good results. Waste of money.

I didn’t feel any warmth, but my neck started to hurt-there were red marks on my neck where the magnets were located (had it on less than 10 minutes). Felt like burns. Put cold washcloth on and eventually pain and red marks went away.
