Is ShopBack legit?

I’ve been searching for cash back and micro task sites, and found ShopBack. It looks pretty promising. I’ve seen positive ShopBack reviews on other sites. They offer deals at a lot of online stores where I shop. I’m a frequent Amazon customer, and it says you can get cash back on every Amazon purchase. Looks like they have surveys and games too.

I want to try it, but I’ve been burned by a lot of these sites. I don’t want to install the app and spend time with it just to find out they don’t pay.

If anyone has experience with ShopBack, I’d appreciate if you can share your ShopBack reviews. How reliable are their deals? How much have you earned? Do they pay out?
