I bought the Grabber 18 Hour Body Warmers (30 Units) for my family to help us stay warm during chilly days and to keep a few stashed in our emergency bag in the car. With two little ones and a husband who loves being outside, having dependable warmth ready to go is essential. These warmers are so easy to use, just shake to activate, and they begin warming up quickly. The heat holds steady for many hours, and I've been impressed with how well they last, especially during long outings or just cozying up indoors. They’re nice and big, which is perfect for better coverage, but I was a little disappointed that each package only has one warmer.

Very nice size. The warmth is long lasting as it is advertised. Keep shaking it to reactivate the heat and make it hotter. Keep it in your pockets to feel the warmth closely with your body. Was outside all day and I was kept nicely warm all day.

When they say 18 hours, they mean it! These hand warmers get so hot and stay that way forever!I like to pop em open and put them in my sleeping bag when I am winter camping to pre warm my sleeping space. When I wake up the next day they are still hot! Move into your pockets when you get out of bed and have enjoyable nights/mornings every camping trip.

Exactly as described. Purchased for two uses--one to keep hands warm while out walking my poodle Zoe and second to wrap around my hummingbird feeder to keep nectar warm. Heat lasts all day. Thank you.

My husband works outdoors and starts every winter stocking up on these hand warmers. After a lot of trial and error, they are the most consistent hand warmers he’s found, staying warm a full work day & for hours after he gets home.

I bought these to use during deer season in Pennsylvania. The weather here can be pretty cold that time of year. We can have mornings in the 20's, and it never gets above freezing in the afternoons. I put these warmers in the two vest pockets in my overalls with a medium weight jacket over top, and they keep me nice and warm all day. Also they stay warm for the full 18 hours as advertised. If you are a tree stand hunter like I am during deer season they are great to have on cold days. I'm going to order more.
