I am very disappointed after buying lg water purifier model WAW73JW2RP.I have changed its membrane in may2016 after paying money of more than Rs 3000/ but only after 45 days again it was not working.service centre has changed it but pathetically it was again damage/not working in again after 45 days and they say to pay more than Rs 4000/ for it.My concern is that how can any one has to pay for filter / membrane in every 45 days however other companies purifier is working more than one year.it means lg quality for this product is very poor. lg is also not assure me it will working for at least 10 month or a year.I also recommend to people not to buy this product as quality is not worthy enough to money.hence please no no buy this product otherwise only headache like me for future.if u buy this product certainly you will be in trouble and trap by company as no option to pay for service because u have to pay lot for this product and costlier than other same product.
