Summary of my purchases LG = CAUTION not you also trapped: * I bought a TV LG LED 42LB5800 (Wifi internet very handy for navigation) * I bought the remote LG AN-MR500: voice function, mouse cursor on the TV screen gesture detection / Gyro But I'm fooled / by having poor customer technical service and LG. The remote control has NEVER wanted to sync with my TV to the mode "mouse cursor / Voice Mode / OK key via Roulette" Call SAV LG ==> reply after 30 minutes of test = Remote HS ==> I returns New remote control received 4 weeks later (exchange on Pixmania long delay following stock) Retry on LG TV ==> Remote still IMPOSSIBLE to validate / save / synchronize with my TV Second call for service LG ==> 30 minutes test / test / reset = always NOTHING works! He tells me = + IR card motherboard failure Module It sends a technician home. He spends 1h30 to test my remote control + disassemble / assemble new components open the heart of my brand new TV (1 month!) ALWAYS down !!!! He calls his HEAD = Problem technician found ==> to my TV with this remote control you simply the LG AN-WF500 box !!!! For in fact the remote control operates on two transmission modes: * Infrared (who always walked carefree) * Bluetooth remote control for internet and multimedia features No Bluetooth receiver module on my TV !!! But the ranges above mine YES !!! Result = all product reference time energy losses + telephone exchange for a simple Bluetooth compatibility problem !!! It's not for lack of giving LG references / models / serial number of my LG product (TV + remote control) = they should immediately strike and say he was necessarily the case BLUETOOTH LG AN-WF500 !!!! In fact this LG AN-WF500 case is WIFI BLUETOOTH + but the media called as ... ??? I see too why ??? POSITIVE CONCLUSION: - With this LG AN-WF500 USB box + remote control my LG AN-MR500 I take 100% of my Internet enabled TV LG LED 42LB5800 NEGATIVE CONCLUSION: - Mediocrity and low-end professional technicians and LG Phone Service - I tried to negotiate with the free offer of LG LG AN-WF500 limp for compensation for any loss of time / money / apepl phone, but LG has not wanted to make a gesture of goodwill of € 35! !!! DEPLORABLE !!!!! LAMENTABLE !!!!
