most older cd players... home and car, have trouble reading CD-R's... and especially CD-RW's...

I think the reason it didnt catch on is its only a 3 disc changer... maybe if it was 5 or 6 it would have been better... but being its only 3 disc, there is still a lot of changing CD's to do... to me, i'd rather just hit a button and have the CD slide out, instead of messing around with that magazine while driving.
