Q: The instructions were very limited in how to change music or display the time without also turning off timer. All I got from the directions is, turn on player, press start. Not much else there, but I'm still looking for a way to make it work properly like my old player did.

A: Bad review

Q: I had been planning a trip to the Galapagos Islands, and this guide was required reading by the tour group guide. The guide is thorough, providing information of interest and useful for all travelers traveling among islands, but the format of this book severely detracts from any pleasure of seeing them. There's an interactive CD-ROM provided which allows you to see photos that were previously in the book, but not the whole trip. Additionally, there are many grammatical or spelling errors.

A: Bad review

Q: Okay game. You gotta beat all the enemies for a good ending. Otherwise I would have thrown it out my window.
