Sandhi Sudha is totally useless.DO NOT BUY SANDHI SUDHA JUST BY WATCHING AGGRESSIVE ADVERTISEMENTS ON TELEVISION. Even 15 days return back gurantee is a myth. I have a very bitter experience of our reviewers recommend us with telemart network as I bought Sandhi sudha online on 20-Jan-11 (order # 985). Received order on 26-Jan-11 and logged complaint for return back on 02-Feb-11. Telemartnetwork people are keep on saying that my request will be processed today. They do not have any mechanism to give you complaint reference number so that you can track them. Customer care is even one step advance,they do not want to listen you and hang the phone as you are talking to them. Totally a fake and worthless company. Would request patients/users to do not go for Sandhi Sudha product, it is a totally wastage of money.
