Query: Huh......

Many people who enjoy this player seemed like they had never operated one before. Of course the ESP would work if you "smack it or even drop it". Do you have any idea how ESP works, obviously not. It is stored in an electronic memory for 40 seconds (or whatever) until the song gets to that part. By dropping a player, you physically can't delete this information. ESP - >>Electronic Skip Protection. I say get the $70 ones.
