unreliable product 7

belt purchased in July, seems quite consistent with the description and working properly. After six months of intermittent use, now he no longer display on the screen and the trimmings + and - buttons respond quite random and fantaisite.
It is a device that has no reliability.
It probably pays for television advertising but not the quality of the product. The client does not préossupe the masses.
I do not recommend this unit.
