The product is fairly good value. The only downside is if you want a measure of when not if unlaces randomly. Let me explain: for a rather steady march there is no problem, but for short displacement of less than 7 seconds nothing is recorded. Indeed precision is lacking in the description (but present in the instruction manual supplied) is that all movements under 7 seconds are not taken into account. In fact counting starts well from the first steps, but they are counted only from 7 seconds to go. The product would be perfect if 7 seconds were adjustable.
