Thank you for viewing. Returns are not accepted, so please consider after confirming the listed contents. I purchased this at Workman last year and used it for about a month. It's the 2024 model. Included items are the box, the Peltier vest body, the included battery, a spare battery (non-genuine), cables, and the Peltier vest instruction manual. The cable is used when using the spare battery, but the perceived temperature seems slightly weaker compared to the genuine battery. I press the button to turn on the battery, and I've experienced the battery turning off during use of the vest several times. I will ship 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.
