This is not a scam!! Several people have asked if this is legitimate item and I can assure you it is. Look at my reviews. I am just a mom mostly selling clothing. This is the first electronic thing I have listed. Anyway, if you are genuinely interested in this vest I am happy to send you a video with me and the vest in it. Shoot me a message if you are interested and I’m glad to put any suspicions to rest. I Bought for my son for Xmas last year and he literally used this one time. It’s super cool. Brand new. He didn’t just didn’t have the patience to put it on as a preteen. Make me an offer! Liking to sell quickly.
