Digital LCD screen counts up to 99,999 steps before resetting. Automatic sleep mode turns off pedometer when not in use while retaining step total. Uses DC 1.5V AG10 battery (included). 1 year average battery life.
These things are worthless–they don’t work at all. They count “steps” when you are sitting down, driving, etc. Then they reset at random or turn off. Not even worth $1.
