The Polar Crystal Loop is an activity tracker that is also trying to be an elegant piece of jewellery. In my humble option it looks tacky, its silicone wristband has been adorned with delicate Swarovski crystals which clash with the thick strap, it looks tacky and half hearted, aesthetics aside this doesn’t have as much to offer as the A360. You need the Polar H7 heart rate monitor to use the Energy Training, Training Benefit and Heart Rate During Training features but you do get the sleep tracking feature. It links to your phone for notifications and it tracks your calories accurately and it works with the app to give you daily, weekly, monthly and yearly feedback. It offers less and looks worse than the A360, for the price you have to pay for a bit of sparkly branding I would steer clear of this one.
