After the successful Paisapay, we will be given a chance to rate the supplier on couple of aspects.
In the same way an option to rate the product condition and how the product working after due course of time need to be included.
This is just because there may be cases where the good was working good at the initial stages and may degrade after a while of using it.
In my case, i bought an ear phone of sony which worked very nicely for the first month and later one ear piece suddenly stopped working.
So if at all there is a option for the one who bought the item to give a feedback or review of the product bought, it will surely be useful for the future buyers of the product.
