Purchased new on Amazon in 2023 and worn twice for short periods while camping. The ice packs were also only used twice at that time. I haven't used it for work. The battery has only been charged once. Accessories include the main unit, battery, and four Torito ice packs. Two Torito ice packs fit perfectly in the back. It's a ready-to-use set. Please note that this is a used item, so no returns or refunds are accepted.
