Skymaster TV LED 32SHA2000 SmartTV: User Experiences and Potential Issues in Hostel Environment

I would like to buy a dozen or so TV sets for the hostel. Does anyone have experience with this or a similar model? What problems may I face? Problems such as resolution, sound quality or contrast do not interest me, but if it turned out that it regularly crashes or in smart, for example, does not play video on the Internet, it would already be a problem, By the way, this video does not play LG that I bought 2 years ago and the website says that there will be no software upgrade
I will be grateful for specific information instead of general truths that it's better to buy Philips or Sony

Generally, Smart in TV lives for 3-4 years. This is what it looks like now.

If it is to be simple, I would bet on WebOs from LG or Tizen Samsung - I would let others go.
Except that in budget models from the lowest shelf, you will not find efficient systems ...

Thanks, I'll take 1 for the test, I'll see how it works. It doesn't have to be a rocket. I mean more general reliability and whether there is a face like that an application does not work anymore because they changed the codecs or something, or it is known for sure that in six months it will not work. That sooner or later something cannot be handled is clear

Great, thank you!
