product is good but the service person who came for installation was very cunning when he called initially to inform us that hes coming he asked us if we wanted the stand too i told him clearly that i already had a brand new stand after coming to our house he informed us several times that he brought the stand anyway and it was free of charge when he saw our stand he told us his free stand better so finally i said ok immediately after installation he asked us to pay 1500 for the sa
