Any good survey websites besides Milleu and YouGov?

Other than Milieu & YouGov, I also use ApiaryBuzz. Each survey delivers as it promises (= 2 minutes), so it’s not taxing on my schedule. There is a survey on alternate days, so it’s easy to incorporate into my daily life too. I find that I like to do an ApiaryBuzz in between tasks; a cognitive break, so to speak

For survey apps, you can take a look at Google Opinion Rewards. Wei Yi also included Shuga (https://www.shuga.io/) in his article which you can take a look.
