Not very reliable and can not reset

Certainly it is not bulky, but this is not enough to make it as efficient and fair as it should be. The actual length of the pitch (therefore, measured by its user) is not specifically taken into account by the apparatus, and this results in an erroneous calculation of the actual distance, displayed higher. Contrary to what is stated in the instructions, my pedometer has not reset to 0:00, and therefore retained the next day total not recorded yesterday. I tried to reset it by pressing the reset button but this operation had no effect on the reset (RESET) of the total no. Only weight parameters, size, etc .. are kept, but not continue to run ...! If someone has found manipulation 'thank you to know, otherwise the manufacturer to remedy because this function would seem to me, very helpful.

I bring a corrigendum to my first review on August 27 the only reset: it is done automatically at 0:00, after a few days of use!
So there is more need to remove the battery to do this.
