I bought one of these only to find that the controls on the front panel had dirty fingerprints on them. Amazon sent me another and this had the same problem. Thinking that this was a batch that might have been affected I purchased from a different source and found they were also covered in dirty fingerprints. There was no evidence that the package had been opened.
I subsequently contacted LG who don't seem to be too bothered. The first person told me that they wouldn't have been sent from the factory like that so it must be the supplier who is opening them to e.g. check contents. The second LG support person told me that the fingerprints were a guarantee that it had been officially checked by LG to ensure it worked! I have sent all items back and will buy from an alternative manufacturer.
I suggested they invest in gloves.
