  • The Best TV EVER

    from Lachine, QC on April 10, 2019

    Bought this online, Open Box...bought 17 Mar, got Mar 20 !!, bought it because of the V stand, it can be put on a narrorer cabinet...was Easy to set up, even for me, i think maybe because it was already checked / calibrated by "Geek Squad"..connected easily via our cable, a few passwords later with the cable remote it WORKED... I luv it, my husband did not want one (so big)... well guess who,,,,, is glued in front, golf/sports/ etc... the sound is very good, loud enough for our room 12/18, It is sitting beside the patio door, west side of house... the picture is great even in bright daylight.. fun to watch action movies, ie as in the 'life of Pi"..& my dogs like barking at the strange animals now on the big screen :) So, Now i will wait for my computer nerd son to teach me how to use the smart features... very good price... & so far very happy with the purchase, and the Best Buy Service...especially in their stores..
