They are incredibly easy to use. Unlike some hand warmers or heated gloves that have different settings to master or need charging before use, using them is as simple as removing them from their outer packaging.
Activated by air, they started to heat up almost straight away. I found they became noticeably warm in just over a minute without any further action needed from me. While the warmth felt pleasant when I held the sachet between my hands, it felt even more comforting when I popped it inside my gloves, creating a more substantial warmth that seemed to radiate across my palms.
Due to their small size and lightweight nature, the Hot Hands Instant Hand Warmers were really discreet and unnoticeable when used inside my fingerless gloves. I was able to continue typing when working from home without them feeling bulky or restricting my movement.
