I have bought the pedometer because I wanted to bring some excitement to my life, but I lack the time to exercise. my cell phone battery should not be charged. In addition, the positive reviews convinced me regarding the accuracy and I can only confirm this. the operation of the device is very light, and manual time change worked. I use the pedometer every day since the end of January and the battery still holds, was tendered a shelf life of up to 3monaten
