i purchased F101 model in nov.2012. within 15 days the mobile stopped working (display problem). the company replaced it by model F105. after 2 months the power on/off switch broken. even though i used it for further 1 year by using tooth pick/pin to switch on/off the mobile.since last 3 months it is totally useless as display is collapsed.i was very impressed with performance of ONIDA T.V i used so many years.
