I use the Body Media Fit device, previously called the GoWear Fit. It is the same thing as the Body Bugg and made by the same company. These devices do a better job showing the calorie burn of some activities over others. For instance, running and walking they do a great job with. They don't do as good a job with cycling. However, you can get better results by moving the unit to your calf while you cycle. That's what I do. Roller blading, however, there is no fix for. You can take off the unit and edit the time you have it off body. I hope this helps. Let me say that in spite of its shortcomings I think these armbands are fantastic for providing motivation to move more and I lost over 25 pounds in less than a year with mine, and I am at goal now. I lost some before I got the GWF.
