A pedometer which I 've used for ten years broke, and I bought a new one at a drugstore. How small it is!
It is only 22g, and has far more functions than the old one.
MT-KT01 made by TERUMO can count even how much calories you burn not by walking but also by any other daily activity. Even the day you miss your walking time, for instance, when the heavy rain falls or just you don't feel like walking, you don't have to be discouraged.
The tiny trainer, in your pocket, always shows "now you are consuming calories." It seems to me that it is a very patient and generous private trainer.
