I have a Fitbit Charge and wear it pretty much 24/7, with the exception of the bath. I've lost nearly 2 stone as well which I attribute to not only diet but moving a lot more. Mr F and I walk everyday and although I'm not hitting the 10,000 steps daily target, I'm hitting around 8 - 9,000 steps a day. It a great motivator and also has a few nifty features such as a clock, alarm, and it even vibrates when I receive incoming calls on my iPhone. I use the Fitbit App on my iPhone as well as the website and my Fitbit syncs over Wifi with both. Mine monitors sleep as well and its interesting to see my sleep patterns at night and how many times I have waking periods, as I'm completely unaware of those during the night! I also bought the Fitbit Aria scales so when I weigh myself, it automatically updates my Dashboard and its a great motivator to see a graph of my weight loss. The Aria was expensive at £99 but I needed new scales anyway. The Aria even recognises me when I step on it. It can also have multi Fitbit users and can recognise each user. My husband just uses it to weigh himself (he doesn't have a Fitbit). I'd be interested to see how much a Fitbit Charge will cost on QVC - mine came from Amazon for about £94 odd and QVC are not exactly renowned for being competitive on price. Maybe they will bundle it with lots of useless accessories like they did with the iPad to justify the inflated price. We shall see.
