**Perfect Fitness Pedometer - Step Counter with Distance & Calorie Tracker for Walking, Running & Weight Loss**

I bought two of these, one for my boyfriend and one for me. We were trying to achieve a healthier life style by walking 10000 steps a day but didn't want to carry our phones everywhere we go.It worked well for us for the first few days. We loved its small size and the ability to set a daily goal. We liked it enough to put up with the obvious clicking noise that it makes with each step that we take. However, both pedometers stopped tracking accurately soon after without being dropped or anything. We tried for three weeks and finally gave up. There were days that we carry both the pedometers and our phones to compare the step count and consistently the pedometer gets 5-8 times lower count. It was sadly a waste of money and I really wanted it to work.The fold over clip for attaching the pedometer to a pocket or waistband is way too tight and not adjustable. I never use it.Muy sencillo, muy fácil de configurar. Mal que no se pueda apagar, por las noches por ejemplo, veremos lo que dura la pila. El clip resistente y robusto, mantiene el dispositivo en su lugar. No hacer caso a la formula de medición de longitud de paso, mejor realizar lo a medicion de 10 pasos, es más exacta.
