Query: Product short-commings not reflected in price

Not stated anywhere in the manual - if you are using a USB flash card that has more than 2004 pictures, - some pictures will never be displayed. The frame will display only the first 2004 pictures.ALSO the random shuffle mode is not really random at all, the same pictures will be cycled over and over like 1st, 5th, 8th, etc, but other pictures will never get displayed.Customer technical support is rude (they do not even pretend to be polite and hang up on you if you ask questions tey do not know the answers to) and they are not knowledgable. I am an experienced computer engineer and my opinion is that this piece of electronics is not a quality product, however the price is quite high and does not reflect the short-commings.
