40 inch TCL QLED SMART TV.
We picked up the TCL TV at the store. It was package well,, even included plastic wrap on the full screen. My son loves it. The color and clarity is excellent. We are very please with this set. It is actually far better than we expected for the price. 40 inches turns out to be a perfect size for a 10' x 12' bedroom. Thumbs up!
