I've been using Crowdtap since fall of 2019, and had no problems - except maybe one time they forgot to send me the gift card I redeemed, but I contacted customer support and they sent it out pretty quickly. I always take the surveys that offer 30+ points and only take the 3 or 5 point surveys if I have extra time. That way, I reach the 5,000 point threshold fairly quickly. I think I've cashed out about $300 worth of gift cards over the past roughly 2 years, which isn't a phenomenal amount of money, but it's a nice little side gig. Plus, I like answering the questions, especially the ones related to food, beverages, and the restaurant industry (as a fan of healthy food & new food trends myself).
I did get one sample one time - it was a deodorant made from bamboo fiber or something like that. I think I forgot to write the review about it, so I don't blame them for not sending me more samples, ha.
Overall, Crowdtap is the only survey site I've stuck with in the long run. Swagbucks was a giant waste of time, in my opinion, and all other survey sites I've tried I've maybe gotten like $5 out of.
Definitely give Crowdtap a try. I've always answered questions truthfully and given full, well-thought-out free responses, and I've never had any issues with the site.
