I bought my first heated vest from ORORO about 5 years ago and it still works like brand new. How ever it does not look brand new. I was a metal fabricator and I also have 40 acres that needs to be maintained so that vest has been through a lot of wear and tear. It has tears and rips in it, the battery pocket is almost torn off, the pockets have holes in them on the inside but it still gets warm when I turn it on. I bought this vest because of the size of the battery and where it was located ( small and out of the way when wearing it while working ). I bought this new vest to have something that looks good when I go out in public and I just need a light weight outer layer that I can turn on if I need the extra warmth. I had one of the same vests for the same reason but I gave it to a friend last winter because he needed it so this one is for replacing that one. ORORO makes great light weight heated outer wear so get yourself one and buy a friend or family member who gets cold easily one also. Both purchases will make you feel good.
