I like the 4th sound preset for its bass and treble levels. Digital LCD Function Display - 500 sec. Does not store when powered off. A lame idea I haven't tried to use. My first impression was that it is built very well.
Buttons have a firm click and the general feel is rugged.
I used to press the buttons alot more to advance one song at a time. Now I've found that if I press the track forward button twice and hold it down the tracks will scroll forward very rapidly. I also use the random play mode quite often. Some have said the 800MB disks do not play in the MPTrip. I have not tried them but the 650MB all work well.
