The playback of the music on this unit sounds good. It has many problems that outweigh this positive. The worst problem is that it caused my Handspring to lock up quite often causing a soft reset and sometimes a hard reset. It also ate batteries very quickly. I even got a AC adaptor when I was loading the files and a AC adaptor for the car. It still used batteries too quickly.Also, It takes way too long to load mp3 files on onto it. Innogear was offering a speedloader to load the mmc file faster. Minijam uses a propietary format on the mmc card so you can't just buy any mmc card reader.You cannot store any kind of file except for mp3 on the mmc cards either.This is a product that has potential if Innogear will address all of the above problems.
