Query: Ego boosting but not accurate

I purchased this pedometer for it's ability to count steps in your shirt pocket. Unfortunately you must 1 have it vertical for it to count at all and 2 you must stop breathing for it to count only steps. I was able to sit at my desk and it would add steps while I was working on the computer averaging about 300 steps per hour, very gratifying to my ego but not what I wanted. It is extremely accurate in a pants pocket or attached to a belt and gives the same count +/- 4 steps as a manual count over a three mile course. Has some fun features like calorie count and aerobic timer. I bought it though as a drop in my shirt pocket pedometer and it is simply not at all accurate for that purpose.
