Product Name: WZ-5 Wind Core Ice x Heater Peltier Vest PRO2 Manufacturer: Workman Purchased in a physical store in June. I felt that the Peltier part was uncomfortably cold, so I only used it for about a week. I wore it over an inner layer, but there are fine scratches on the cooling plates. There were no problems during use. All accessories are included, including the warranty.
