I had purchased a CS2 battery from ebay from Deals_mantra, received the same as per the indicated timline, battery had started behaving erratically after the charging, (mobile gets switched off when the battery is showing 50%) I posted this feedback someone called from deals mantra, saying they would replace the battery and asking me to change the feedback. I have not got the battery it is almost 2 months now 24th April was the date of purchase. with 31182594254 as transaction id.
It is precisely for these kind of reasons that I shy away from shopping online (feeling cheated, amount irrelevant)
