INTRO:
If you purchase this television expecting it to blow you away, please remember the price you are paying for it. In comparison to the competition at this price, I would say with confidence that Westinghouse has created a great budget 4K UHD option. While it's smart functionality is limited in comparison to my 4K Samsung TV (which I paid twice the price for), it is objectively so.
SOFTWARE:
The Smart TV functionality includes the basics such as Netflix and YouTube. Selecting YouTube videos from my phone, then casting them to the TV is my preferred method, but the TV app's UI is certainly sufficient (although much slower than your smartphone's processing capability).I spent some time on YouTube watching some of my favorite 4K videos, and the picture is crisp. I've had the issue of getting the Wi-Fi to stay synced after shutting the unit off then turning it back on at a later time, but it only happened once. That could very well be my network, as well. The television's wireless only supports 2.4GHz networks, but I didn't have issues with buffering or the like with my network (albeit, I have two Apple Airport Extreme 802.11ac routers for a very strong connection). Alternatively, ethernet is available, but I have not tested it. That being said, I'd recommend purchasing a set-top box (Android TV) with 4K support if you want to get the most out of this TV.
DISPLAY:
Going between the Samsung and the Westinghouse, I've yet to complain about the Westinghouse's panel. It holds up well, but I'll be honest and say that I haven't bothered to spend much time comparing the panels. Objectively speaking, unless you're accustomed to OLED displays or the most high-end, you will likely enjoy this display. It's native resolution is 3840x2160 at 60Hz. It's fluid, not like 120Hz, but I have no complaints in that regard.
SOUND:
In terms of sound, it's nothing to brag about. It definitely lacks a wide frequency range. Even with the built in EQ completely flat, it just doesn't compare to my Samsung's sound. It's not horrible by any means, but as somebody who enjoys high definition audio, I'd recommend getting a soundbar or other home theater setup. That being said, it does get pretty loud without clipping. It can probably be described as a warmer, or slightly muffled. I'd have to run a spectrum analyzer to give the best impression.
ASSEMBLY:
The assembly was pretty easy. Just follow the instructions, and you'll get the stand on without issue.
OVERALL:
I'd recommend the product--especially at this price. I don't think there really are many 4K UHD options at the price I paid that give you the feature set and quality this product provides.
