How often do you find product recommendations on Amazon /fkart/ecom sites useful ?

There's no option of 'fairly often' to bridge the gap between Rarely and Mostly.

I no longer trust them. The last product I purchased, there was a gift coupon of rs50, where if I give 4 and above rating, send a screen shot to a WhatsApp number I will get Rs 50. I did that and got 50.
I went to a restaurant , a fairly new one. They offered an ice cream as a compliment if I give good reviews in dineout.
