    I love this tracker. It has so much going for it that I can't do anything else but recommend it.

    When I was looking to buy an activity tracker , I compared a few to see which was the best 'fit' for me. Eventually it came down to the Polar Loop and the Flex.

    And as much as I like the look of the Loop, Fitbit have nailed it with the accompanying smart phone app and website.

    The Flex itself is subtle, secure and swim proof. I also love the fact I can take the sensor (it's tiny!) out of the wristband and pop it in my pocket if I want - something I do at work.

    It accurately records steps (I've tested it against a number of different step trackers) and is a brilliant sleep tracker. If you forget to activate the sleep mode (or fall asleep beforehand), just go to the app or website and add the time period of your sleep; Fitbit calculates your sleep pattern anyway based on your movement.

    The battery life is good (I get around 5-6 days out of it) and the three-or-so-hours charging time doesn't really impact on recording your activity. I would probably prefer a longer time between charges, but I'm just being picky.

    The website is just fantastic and gives you the option of linking to numerous other services to accurately record your activities and calorie intake/burn.

    The smart phone app links with the Flex by Bluetooth Low Energy. Saying that, you don't need to have the Bluetooth switched on all the time, just switch it on to sync your data. The Flex also comes with a USB dongle to wireless connect every 15 minutes if you are within range.

    So what don't I like about the Flex? Nothing.

    Love fitbit. Not strap

    Iove the fitbit itself but I've almost lost it a few times because the strap is not secure at all.
