Terrible experience !!! Our cardiologist prescribed using this company to monitor a heart condition for a month. Preventice sent a kit comprising of two monitors which took a week to arrive. One of the monitors stopped working in 5 days. We called Preventince and explained the situation and they agreed to send us a replacement monitor. The replacement monitor took three days to arrive despite us asking for it to be sent over night to us and as if that was not bad enough, the replacement monitor did not work at all from the moment it arrived. We reported the problem to Preventice again and they said ti will take 5 days to get another monitor delivered to us. There seems to be no quality control performed on the equipment being sent out by this firm. I will be conveying my dissatisfaction to the cardiologist and will strongly urge him to stop recommending this company's equipment to his patients.
