So here's the scenario.
You think "I need to understand how my calories are burning off, possibly what my sleep patterns and heart rate are like etc etc" , so you look around and read reviews/ offers/ differing types of these smart watches and decide that the one for you based on what you want is the Fitbit Flex 2, you don't want an all singing and dancing one that will work on the top of Mount Everest, or be water resistant to enable you to visit Captain Nemo on the sea bed, so you visit your local Argos read the description on the sales bumf and it states compatible with over 200 android smart phones or via Home computer, you then think OK your coming home with me! so you buy one.
Now you get home remove from the box your new toy and plug it into your USB port to charge it, once charged you then go to set it up only to find that, a) it doesn't work with windows 7 (and my computer does not have wireless option) but it works with windows 10 which I do not have!!!!!!!!! you get so far through the set up menu and then it says plug in the wireless dongle, Er er What dongle, b) the Fitbit Flex 2 doesn't come with a wireless dongle, so now you go to good old Amazon read through all of the options and find that a 'dongle' is available and will work on home computers running Windows 7, so you order it (now I have to wait another 3 days for it to arrive.
Now after a few choice words that would make a Nuns habits hem curl up and some stomping around the house you calm down.After that failure you go to set up/sync the fitbit with your mobile phone, only to find that the HTC One X is the only mobile in the HTC range that is not compatible as it has an Android system on it that is 4.2.2 and you need at a minimum of 4.4, so as the phone flies across the room closely followed by the fitbit you go; "hang on a minute" when you notice that your heart rate is through the roof, your out of breath due to all of the rampaging around the house, your sweating profusely.
Eventually you calm down even though Β£70 appears to be wasted (until the dongle arrives) because you realise that you have just done over an hours exercise with out knowing it, I don't care what anyone else thinks I COUNTING THIS AS MY DAILY EXERCISE!!!!!
Part 2 to follow, when the dongle turns up
