Good, well-rounded player. Delicate hinge, however.
I standardized on Panasonic for portable DVD players after previously having good luck renting them from inmotionpictures.com. They are not perfect as this is now #3 unit, in 4 years. The first one acquired "H03" syndrome (an error code), basically means the reader head can't read the disk (but the syndrom is that the disk is actually fine). This was not an LS91 that failed.
All the Panasonic players models I have had have a display hinge which articulates in 2 places. This is a downfall as #2 (LS90 I think) failed due to this. I wouldn't place all blame on Pana, as the prime user is a 12 year old boy.
So we are on #3, a used LS91. The LS91 has great battery life. If you get a used one, you might need to buy it a new battery, FYI.
