This is the worst Opinion rewards as you cant use your earned rewards anywhere but remain as rewards in your account. I have been using this Google opinion rewards for the last six months and till date I’ve got ₹ 336. 85 into my account. But what is the point of earning those rewards when you cant use them anywhere. I tried to buy paid apps from playstore but it doesn’t work, this rewards is not applicable here as it asks for bank card details. The rewards can’t even transfer to any digital wallet. I feel like I wasted my time.
