In view of poor ratings of addmekart but the choosen old version is not available (updated fancy looking version is available at Flipkart at similar price) I dared to purchase Boat Rockerz 650 headphone from addmekart "as precaution on COD basis".
They have contacted me for order confirmation. They have delivered it but without original packing, user manual and cable (but i couldn’t find any wear of use) in very poor genericpacking. Now no body lifts the phone. Luckily the product is functional, 3 moths are over it is reliable , the battery drain is very low it may last 3moths in shutdown condition . Hence it is better to avoid this company.
