I have the HiSense Model:F24V77C in my bedroom for the past 14 months, and am very pleased with the set. I recently looked at the Model:F40V87C at hhgregg with my 9 year old. While looking at the set with the salesman, my 9 year old picked up a remote from another set and started changing channels. The catch was that the remote was for the same sized LG set. Although the remotes were different in appearance, both remotes were fully functional on both sets. Being curious, I tried the HiSense 24 inch model remote on the 24 inch LG, no surprise, they both were fully functional on both sets. After researching, there is no information as to "who" builds the HiSense sets, or if HiSense builds for other manufacturers, i.e., LG. As we are all fully aware, there are only a few companies that actually build electronics, and place other names on them for that company. All said, China, like Korea in the past, doesn't have copyright agreements with all countries. Yes, the sets are less expensive and do have flaws, but there is no cost of R&D for the manufacturing companies, as well as using rejected / seconds, of the display panels, equating into a lower end price. And of course we all know that companies do not reverse engineer competitors products, that would be unethical.....(I wonder how many products are being reverse engineered while typing this??)
No, this is not the set for the video critic, but for the average user, I see no real issues. At under $400, two years use, consider it disposable. If you want better support and warranty, buy and extended warranty, or a more expensive set, but still buy the extended warranty. Just as a light bulb, man made it and it is going to stop working. When? Maybe the next time you try to turn it on.
