Over 4 years of usage(purchased it in 2012) and no problems with it.The best part is that it plays movies via USB(even Reads 1TB hard disk) it reads all the latest formats like mkv, mp4 etc.(firmware updates have been released).
No problems as the other user’s have mentioned. This model still gets firmware updates. Picture quality is also good. Overall a value for money and still finding it hard to replace this TV. Best picture quality when using HD connection. Has multiple HDMI ports and USB ports which is quite helpful.
Has a handy remote
