I really love the way this TV looks but my LCD and HD channels have a green tint on them. In addition, every channel has digital artifacts in it. Very disappointing. It's an older LG so it may just be quality that varies from model to model. Too bad as I've had luck with their products. : -(Now if only they would fix those issues because of this TV's price...I will return it. Edit: 11/2013 -- This is not what was promised.

Bad review

The idea of an individual book on my favorite tv show was really exciting! So when the calendar arrived it came in a timely fashion, and though there is nothing wrong with it, I did anticipate that there would be more than one episode in each month.

Good Review

This product performed as expected, and was delivered within only a couple of days with standard shipping. However, the item I received did not have any markings on it showing that it's actually a Toshiba battery. After charging this battery fully, I've been using it for about three weeks, so I'm still unsure if that's what makes it function properly. Overall, since it's such an inexpensive battery, I'd say it's worth taking into consideration.
