This pedometer is the best when it comes to tracking your steps and calories burned with very high precision. Consider it, if you're on strict diet. Be aware, however, that it's not the best option for athletes.
Con Doesn’t work well if accidentally displaced
If you’re not careful about always having this pedometer in the right position (with the lanyard loop up), it tends to over-count your steps. It starts counting in random motions, jiggles and accidental sways. Keep it attached to your pocket, or bra, to get the best results.
