While it was effective with the mosquitoes, the odor was very strong and 2 of my grandchildren developed rashes from where the wristbands were on their wrists (which disappeared after the wristbands were removed).We eventually hung them around the perimeter of the patio and had a wonderful time playing card games under the protection of the wristbands.
This product did not work my first few attempts. I got online and found multiple reviews, many of which were from consumers who purchased from Groupon. All of them said the same thing -- this was a waste of money as it did not work at all. Other reviews suggested it was a scam. It does appear so. Do NOT buy this item!
