Bargain
A very reasonable Tv for the amount of money we paid. Delivery great and installing easy. Good picture quality.

Great Picture Great Value
Bought this last week to replace a Samsung QLED for kids snug. Great price and picture quality on a par with the Samsung. Sound from the built in speakers not the best, we have a sound bar which paired via Bluetooth easily. The home screen is quite busy and the menus can be slow to navigate through but once all set up it works perfectly.

Tv quality
I've had this a couple of weeks and I like the size and picture quality. I would prefer the settings menu to be easier to navigate but setup was quite easy. The price was great and delivery was fast overall this is a quality tv on a budget price.
