I have an overall 3. I had a full coat & a vest stop heating within a week of each other. The coat was a Christmas gift to me from my wife & the vest was a Valentine’s gift to my wife from me. The coat was less a couple years old & since my wife purchased through Amazon, the warranty was for 1 year. Buy direct from Ororo, it’s 3 years & would have been warrantied. So I am out of a coat. Wouldn’t replace it thigh it was only a couple years old. The Vest: I ordered from Ororo.com & it was replaced immediately. I did have to send a picture showing the connector was cut off with scissors as they required. Guess they didn’t trust my word from their troubleshooting. I would have given 2.5 stars if available. Wherever you sell your product, stand behind it the same!! Hope this helps someone before buying.
