I am using the Intex fitrist band for past 10 months. well I personally use it just bacause it vibrates with I would have forgetting my phone anywhere, also it looks good on your hand. but when it comes to perfomance as a fitness band I give it a 2/10! No Accuracy at all! wrong calorie mode count, wrong distance tracking, it vibrates 10 times for a single message. due to which the battery drains faster. every time it is dissconnected it takes 3-4 attempts to reconnect! if you are planing to buy one first be clear about your requirements as it is not fullfiling mine. if you want to buy a fitness band just to motivate you to go to the gym daily and which looks good on your hand go for it, but if you want something for your daily fitness and health calculation with proper accuracy, I would not recommend the intex fitrist.
