Review on 🔥 USA-Made: HEAT WAVE Instant Reusable Heat Pack & XT Large Hand Warmers 4-Pack (3x6) - Ideal for Camping, Hiking, Pain Relief. Try the Click Heat Solution! by Charlie Dillon

2.5 hours? Yes No. Not even close. I am very disappointed in this product and would not recommend or buy it again. I bought them because I work outdoors, I paid extra money thinking they would last 1.5-2.5 hours, I figured four of them should last a day. Not correct! They each lasted barely 1/2 hour. are they warm Yes, but only for a fraction of the time I was led to believe. So I'm out in the snow working with my hands on cold wet steel and when I first used these heating pads they didn't work. Thank you guys enjoy my hard earned money. waste product. Doesn't do what it says. you have been warned Update 12/2, I still had them in my work bag and my hands were freezing so I used them. I've used it and warmed it up before. Well, don't you know, this thing just popped up in my pocket! white shit everywhere!.
