BodyMedia Armband through the Jillian Michael's site?

I don't own one of these, but the best deal I've seen is at Costco.
The price is currently $119 and it comes with a 1-year subscription (as opposed to a 3-month subscription).
Not only that, but Costco has a great return policy.

I don't have a Costco membership, buy my sister does. I keep wavering ... do I want a Bodymedia? Or do I want a Fitbit? (I'm leaning toward a Fitbit since I enjoy logging my steps.)

I got one in December and it's been a real eye opener. I find the Bodymedia very useful. Make sure you get the bluetooth one.

I'll add another vote for Costco so you get the 12 months free, plus you can take it back if it fails (like mine did)

Just checking OP, are you from USA?

Has anyone used the calorie burned number to figure out the equivalent of TDEE-.20? I'm just curious - I see a lot about that on MFP, but it involves a bunch of calculations on figuring out your TDEE, which I assume isn't necessary if you are using the BodyMedia?

Here is my review from a previous thread:

I've had mine for over a year. I did take a couple month break from it when I wasn't really working out or eating well, but I've been wearing it consistently since June now. I have the Link version with an Android phone, and I definitely would NOT recommend it. It's a pain to get the bluetooth to recognize it - when it does sync, I'm never sure what i did to make it sync, and I can't usually get it to do it again. It's just not worth it. I also cannot use the Activity Manager from work - it won't load. I went through customer service a few times, and the only time they could get it to work is if I cleared all my cache, history, and temp files, then completely shut down all your browsers (I tried it on all of them), and restart your PC in order for it to load. And then, when it times out, you can't load it again. I just gave up and started using MFP as a way to log my food and it links with the BM, and it's mobile ap is MUCH better, so that is the fix there.

As far as accurate - it's ok. From the beginning, the sleep monitor shows big chucks of time (at least an hour, sometimes more) in the middle of the night when I am supposedly up - not just lying down, but actually up and out of bed. I can assure you that I don't sleep walk, and I haven't been able to figure out why it stops recording my sleep. So, the accuracy of the sleep data is in question.
It doesn't register any of my weight training or isometric exercises as even moderate activity. I do aerobic activity daily - walking/running, and it will recognize that down to the minute, but when I am done, I do weight lifting and/or ab/leg/butt exercises, and it doesn't show them as exercising at all. I’m assuming it is ticking up the calorie burn.

For steps, I also question those. I was on vacation and walking about 3 miles every morning, and it would record 5-6k steps. When I got home, I switched to my 4 mile walk, and it would only record 3k steps. When I had a pedometer, my treadmill 3 mile walks always got me at least 6k, but now 4 mile walks were not getting me even 3k. I doubt the accuracy of the pedometer.

For some reason, I figured that the calories burned was different than steps - I could see it being more accurate at that, and it has been, at least, consistent. However, I have had 500-1000 daily calorie deficits, and I have still gained weight. Now, I know I could easily be off 500 calories of eating, so I could see not losing 2 or 3 pounds, but I shouldn't GAIN weight. I now wonder if it is inaccurately inflating my burn.

All that said, I do wear it and use it, but I was reimbursed by my work for getting it, so that is definitely a factor. I'm not sure if I would recommend it, and I definitely would not recommend the link version.

Good luck with it.
