Unknowledgeable
I called customer service as my jacket was purchased from 2017, needed a new battery pack. Lady on phone said I cannot help you. Few minutes later directed me to this website. Ended not being the correct connection for the jacket. Ended up paying 12$ (out of my own pocket) to send it back. I shouldn't have to pay a return fee for someone who directed me incorrectly. Refund took over 5 weeks to recieve back. Needless to say my heated jacket still has no battery pack, and have no clue how to find a replacement battery. Waste of time and money.
