About 18 months ago, I bought a computerized pedometer called Fitbit. It keeps track of calories, steps, miles and also (which is the reason I bought it) it monitors your sleep wake cycle if you wear it to bed. Very cool, and there's a web page I can upload the data to and keep track of my progress.
Well, I have't used it in awhile and I lost the wrist band it came which, which I need to wear it to bed (during the day I clip it to my bra). I wrote the company to see if I could purchase a new wrist band (I specifically asked to buy one).
They're sending me one for free!
