I am using "Lg WF-T8019QV" model since sep. 2009 and till now I didnt face any problem with it.
Its speech technology makes washing easier. One need not to know much about washing clothes as it teaches itself. You can adjust the volume of speech, can change language "Hindi-English". and also can make it mute. Its fuzzy logix function is best in market with which you can wash clothes without any tension of detergent quantity and water.
Also it is very easy to clean. Clothes, once air dried in machine, lookes freshen up and also it removes bad odour. It also have delay function which is of no use as I did not understand the delay function and also never felt its need. If some body knows its advantage then please tell me. So at end, it is worth Buying
