I have purchased this item in before two months for just 5500 rupees in in line. it is used only by swimmers. while operating suddenly I could not certain times to operate . features is more . it also act as sleep monitor alarm . according to me this very costly . in market another product is available with a less and easy operatable system. once when I went to deep sleep I will keep alarm and it will give signal with avery low sound . after the sleep if I see the alarm has been on . so sound is also poor. totally is very costly and hard to operate . since it has a multifunctional system . multi speciality function is not necessary for this product.
