I was kind of skeptical when I did the first survey, I think I did three for Helion. I had only done one mystery shop for them and they paid in Euros converted to dollars on PayPal.
But today I got this e-mail:
"XXXXX, you have been selected as one of the winners of our Covid Safety Surveys! You will receive your Amazon gift card on this email address this week.
Thank you for your participation!
The Helion Team"
Later today, I got an e-mail with the link to the Amazon gift card for $25. I haven't tried to see it or use it just yet, but it looks legitimate.
