Started with a Gerbing jacket but the controller failed after a period. Despite a ‘lifetime’ warranty Gerbing refused to replace it but gave me £10 off a new one. This subsequently failed too…
I then bought a Keis jacket, 6 or 7 years ago, which i still have. The only issue I had was the power lead from the bike failed. It appears one of the cables is broken at the end of the jack plug, probably a result of regular movement / flexing as I connected the jacket up. If you wiggle it around it will work temporarily. I may get around to trying to repair it someday. I had replacement power leads, as I’d planned to fit these to my other bikes but that’s still ‘on the list’, so fitted one of those & have been toasty ever since
I wear the jacket over a base layer & under the bike jacket but with the liner removed. I’d wear the jacket most of the year but, unless it’s really cold, it wouldn’t be plugged in so just acts like an additional layer
