  • Don't order from Bestbuy online

    from British Columbia on June 3, 2019

    This is my second LG TV and I'm happy with it. The interface is easy to natvigate without reading the menu. The quality is outstanding and comparable to Sony or Samsung which cost around 30% more than LG. I won't recommend purchasing online from Bestbuy though because they use Purolator for delivery, who only delivers on weekdays and won't give you a time slot for delivery (they expect you to sit at home all day to wait for your tv to arrive). The customer rep at Purolator said the shipping guys don't have cell phones so they can't call you before they arrive which is not true. Also, there were several damages on the box but luckily the tv itself wasn't damaged.

  • LG TVs are awesome

    I'm loving our new TV! It works perfectly. And LGs actually come with some free TV channels. Bonus in my book.
