Bests & Worsts Reviews from Amazon

Not effective at all for me. Maybe for a light sweater living in the north. I live in South Georgia where the temp and humidity are regularly in the 90's. These flimsy things do squat. Doubling, tripling, doesn't matter how many I wear the result is always the same. Less than 15 minutes outdoors and my eyes are stinging from sweat. Plus, they're way too tight. Gave me headaches. My ratty, old cotton sweatband is much more effective. DON'T trust the 5 star reviews!!! Inside my package I found a card offering $30 for a positive review on Amazon. Companies with good products need not stoop to such deception.
