I am very disappointed for after buying Epresent V9 Smartwatch. This smartwatch is very poor and cheap quality. Materials is very bad quality. This smartwatch has heart beat measure sensor, but when I try to measure my heart nit or others heart bit, this smartwatch is not to able to show accurate heartbeat. Also display of this smartwatch is not working properly. Touch responses is very bad in this smartwatch. Also processor of this smartwatch is very weak. For this, this smartwatch is not working without hanging. Price of this smartwatch is 7000 but no one buy this smartwatch in this range. I am not happy to brought this Smartwatch. Thank You.
