Thank you for viewing. Returns are not accepted, so please review the listed content before considering a purchase. I purchased this from Workman last year and used it for about a month. It's the 2024 model. Included items are the box, the Peltier vest itself, the included battery, a spare battery (non-genuine), cables, and the Peltier vest instruction manual. The cable is used with the spare battery, but the perceived temperature seems slightly weaker compared to the genuine battery. You press the button to turn on the battery, and while using the vest, the battery has turned off a few times. I will ship it after cleaning with alcohol. I cannot accommodate price reductions or exclusive listings. I will lower the price after listing, so please consider it at your convenience. If you have any other questions, please feel free to comment.
