Review: The heat is on.... - These little packs get super hot so the sleeve provided is necessary. Even with the sleeve, it's still a lil too hot. Need them after UFE procedure and it really helps with cramping. Not sure how long the heat lasts since I just started.
Review: If received in good order, produces all the heat you need for a good time! - Good when working but beware that some will arrive already activated and dead! I counted about 8 packs that were already dead! Some (about 2) could not be used for some reason. No matter how we tried to activate the chemical reaction, it was a no go situation. I was happy with the remaining! The working ones were very good in duration and light to carry! Would order again but the failures give me reason to find another vendor or maker. I cannot offer a solution in the premature activation due to the many factors in delivery methods! This item is activated by squeezing or some impact slapping method and that action comes with the normal action within deliveries! Better packing? I do not know! Again, they work and produce heat for a good duration! Thanks desertcart!
