I'm not a big reviewer, but I wanted to share how these helped me in surprising ways...
I've had them for a couple of weeks now. I bought them to keep handy in my drug free "medicine" box. I haven't had any fevers, but found myself reaching for one in a super stressful work situation. My body was overheating, I felt dizzy, etc. I put it on my head and within five minutes, I was completely calm, refocused, and went into troubleshooting mode - Panic Attack Free! Obviously, the cooling sensation played a major role, but I really like how these smell too! It's like an overall soothing experience.
I'm epileptic and have even slapped these patches on when I felt a little "iffy," to avoid seizures!
Honestly, even if you're just hot, you can put one under your clothes and totally cool down, thus avoiding embarrassing sweat spells in social situations.
I posted a video to show the stickiness. It's the perfect amount of stickiness where they don't fall off (even when walking around,) yet there's no need to hype yourself up to remove it. It really doesn't hurt at all.
These are FANTASTIC.
