Query: OK, I guess, for short pieces.

Pro: inexpensive. Secure digital card slot. Sound is OK.Con: About 1/3 of the time I can't turn it on without popping the battery out and back in. I don't know if this is common or mine just has a defect.Menus are a little cumbersome to navigate.Most serious to me is that this player will lose it's place in a file if the player is turned off. This would not be a problem for someone listening to pop music. I use my player to listen to speech. A typical file I will listen to will be one to two hours long. I do _not_ want to have to memorize where I left off, and find it again with with fast forward.
