HI GUYS, BOOKMYOFFER.COM: It is surely a fraud company which sells low quality products, which they buy from random local cheap markets. I saw their lucrative advertisement on website. I wanted to buy 1 power bank and hence visited their website where they were selling power banks just at Re. I could not believe myself. Anyway when I proceeded to pay they added Rs. 500 as delivery charges. As it was a 11000 MAH power bank I paid them 501 rupees as it seemed cheaper even after giving 500 Rs delivery charge.After a few days they sent me a faulty power bank which was not functioning properly. I called them but they never even took calls on customer care.I suggest not to use this site, you will be cheated.Thank you, have nice day.
