I love the Nomad Jukebox and it is a great way to store and listen to music. It is sturdy and goes with me everywhere.
The only major problem with this merchandise - and I mean MAJOR - is that you must use the Creative Rechargable Batteries ONLY. These batteries are awful. They only last about and hour and a half and they are impossible to charge. You are supposed to be able to put them in the player and plug it in to the wall and it will charge them.
This rarely works.
I called the manufacturer to ask what was going on. The customer service rep explained that the batteries have a "memory" and that if they are not TOTALLY out of juice when you plug the player in to charge them, then it won't charge the batteries.
The solution was to buy a seperate bettery recharger you put the batteries in and plug into the wall. This takes 15 hours to charge the batteries, though. (As opposed to the eight hours it is supposed to take when you charge it in the player.) You have to constantly be charging the batteries if you use this every day like me. The equipment is totally useless without these special batteries.
