Initially the chest was described as OK.
After almost 3 months my iphone 5 will no longer recognize now the chest strap.
I have the battery replaced (about 8) ... but achieved nothing.
Have the unit can try a Mitsportler at its Iphone 5S,
did not work well with him.
Now I'm trying the device on the guarantee of be replaced.
I can only warn everyone to buy this device .... is the only way you can
save the preprogrammed anger
Too bad that is ever offered such a thing.
