Hand Warmers Disposable Single Use Air Activated Heat Packs for Hands, Toes and Body - Up to 12 Hours of Heat - WarmSpark

Last much longer than I need, put them in a Ziploc bag and you might get a couple uses out of them. Nice and warm

These warmers are great and they last a long time. Good fit with gloves for your hands but a little harder with shoes and boots due to their thickness.

These hand warmers are essential for my hour-long walks, particularly given the extreme cold of Iowa winters. I am very pleased to have discovered such an effective solution at an excellent price point. Thank you for providing a product that ensures my comfort. I recommend activating them at least 15 to 20 minutes prior to your departure, as this duration is required for them to reach optimal warmth.

Easy to use and lasts about 2 hours to keep my hands warm.

For smaller hand warmers they put out heat for 10 hrs i work outdoors everyday of the year in upper Midwest where north wind doesn't quit. Yes they say 12hrs but after 10 the heat does start to disipait. Ill definitely buy again for price well worth it..

Slow to warm up but I throw one of two of them into a bag before I winterize my outside faucets. Keeps it from freezing.

When I purchased the Hot Hand Warmers - 80 Count, I was expecting a reliable source of warmth to get me through the frigid winter months. Instead, what I got was a smelly, lukewarm disappointment that might as well have been designed to torment the cold and desperate. Let’s start with the smell. The moment I opened the pack, I was hit with a chemical stench so pungent it felt like I had wandered into a factory that manufactures sadness and regret. This wasn’t a faint odor—it was a full-on assault on my senses. Every time I used one, I had to endure the nauseating aroma, which made me wonder if I was holding a hand warmer or a toxic science experiment gone wrong. And then, the warmth—or lack thereof. Air-activated heat? Sure, but only if “heat” is defined as the mild sensation of your palms trying to warm themselves through sheer disappointment. These packs struggled to reach lukewarm at best, and even when they did, the heat dissipated faster than my hopes for a cozy winter. Up to 12 hours of heat? Try a tragic 30 minutes of mediocrity, followed by a sad, cold reminder of what could have been. I even gave them multiple chances. I followed the instructions to the letter—shaking them, waiting patiently—but the results were consistently underwhelming. Pair after pair, pack after pack, they failed to deliver anything more than a faint whisper of warmth, as if they were mocking me for believing in their promises. And to add insult to injury, a few packs never even activated, leaving me holding a useless chemical pouch of disappointment. Verdict? These so-called “hand warmers” are a colossal letdown, more suited for filling landfills than providing actual warmth. Save your money and invest in something that doesn’t smell like a chemical spill or feel like a lukewarm betrayal. Rating: 1/5 stars. If you’re looking for warmth, look elsewhere. These hand warmers belong in the hall of shame for products that over-promise and under-deliver. I’d rather brave the cold barehanded than endure another round of this tepid disaster.

Work in Cold Storage warehouse and my team loves these and say they last longer than any other brand we have purchased.

Excellent.....been god send walking my dogs. They literally last over 12 hours.. the heat is brilliant and they are perfect sizefor having inside my glove whilst holding dog leads

Excelentes, los utilicé en la gran nevada de NYC y me ayudaron mucho, además de su larga duración, sin mencionar que su costo es inmejorable, muy recomendable, solo toma en cuenta que en todos los controles de aeropuertos les causa duda, hasta que los revisan y ven que no hay problema.

War für die Rekruten bei der Vereidigung, bei ca.minus 12 Grad sehr von Vorteil. Über eine Stunde im Schnee

Worth buying it..warmth was there for 10hrs.

Produit très efficace... réchauffe mains et pieds en peu de temps et dure longtemps. A conseiller
