Grabber Hand Warmers - Long Lasting Natural Odorless Air Activated Warmers - Up to 10 Hours of Heat - 40 Pair , 3.5x2"

The best of this ilk by far. Forget "Hothands" sold here and at Costco. Grabber hand and foot warmers actually warm your hands and feet. They heat up quickly, are much warmer and long lasting than any other brand I've tried. I use these for birding trips to Minnesota and Canada in January and February. None of these disposable warmers are perfect, but these are pretty close. I activated a pair this morning at 9am It's 5pm and they're still as warm as they were in the morning.

Warmer than other brands at Costco and Home Depot.

These are great and work very well. Only thing worth a mention, you need scissors to open the individual packets. If you're not careful and nick or cut the pouch, you will be inundated with the sandy black goop inside that makes them work. Not enough to remove a star, just beware of that.

Rated 5 star for easy, clean and 8-12 Hrs of warm for affected hands, etc

These are great to help keep hands warm in winter. My husband uses them regularly. They stay hot for many hours. Buying in bulk helps keep the price down. We have tried the foot warmers and will be buying more of those also.

These are the absolute best of this type of handwarmers and I've tried several before. The heat lasts so long that when I come in the house at the end of the day, there can still be some warmth left.

Five stars for the hand warmers - these things lasted all day (10 hours) on a very cold German day outdoors! One star for Amazon shipping - the outer box was crushed and torn open because it was way too large for the items inside and wasn’t filled with anything to take up all the empty space.

I put em in my pockets, inside my gloves and in my socks. They went out for daily walks at every stop during Late March Norway cruise. I love these things!
