I used this Raptas A1 Bluetooth Smart Watch for 3-4 months. In this watch first of all the quality of this watch is poor.In this watch the touch is also poor because it is not responding immidiately when I choose any app I takes time to click and open the application.In this watch its camera quality is also not good.Its belt quality was poor.Its bluetooth range is not to good.So, I advise not to buy this product because this is money wasting product.
