Fitbit or other tracking device opinions please

I recently got a FitBit One and so far, I love it. I've had it for about 3 weeks. I haven't figured out how to make use of the sleep information and I'm sure it doesn't count floors climbed accurately, but I like having something that accurately counts my steps all day and encourages me to keep active. Tonight, I raised my computer monitor and walked in place while reading an article to get to my 10,000 steps (usually I have no trouble getting at least 10,000, but I exercised less than usual today).

The stairs thing is frustrating. Today, it says I climbed 14 flights - I climbed 2. When it is windy outside (as it was today), it counts extra. When it isn't windy, it sometimes doesn't count a flight when it should. So, I'm learning to not care about how many floors it says I climbed. It might be a great feature to have if I worked in a building with a lot of stairs.

I do eventually want to figure out how to make good use of the sleep information, since I know that getting enough sleep is crucial to good health and weight loss, but I think I first just need to learn my patterns. It does motivate me to go to bed a bit earlier, which is probably helping already.

Consumer Reports recently did an article on several of the devices. I went with the FitBit One primarily because I didn't want to wear it on my wrist. With the One, I can clip it to my bra or a pocket or just stick it in my pocket - whatever works at the moment.

I had a fitbit and hated it, I don't see how something that attaches to your clothes or just sits around your wrist can tell accurate information about what your burning ( had it for 6 months and returned it) so I was able to see if it helped me lose any weight, I lost 2lbs in the time I had it going off what it was saying I was burning. I then turned around and bout a body media core armband and within having that for 2 weeks I lost 10lbs!! This works better in knowing how your body works as the longer you wear it the more it knows about how your body works!! It uses the same way to tell how many steps you do like the fitbit, ** Its patented sensors detect skin temperature, heat flux and motion, so it knows what you're doing, when you're doing it and even the intensity of your effort. Also is FDA approved as a medical device to help in weight loss** Which to me would be more accurate than what fitbit could give. I was able to compare to fitbit as I had the information saved up and it was 200 calories WAY off to what I was truly burning. I know this effected me big time because I wasn't eating the right amount of calories for my body to burn and consume to create a loss. I put my money 100% on BM Core Armband.

THESE ARE MY OPINION AND SHOULD JUST BE USED IN YOUR DECIDING, NOT 100% ON WHAT YOU CHOSE TO DO
