Input:
User Review: For my first MP3 player, I found this to be a very good unit. It is light, easy to use and plays forever on a a single "AA" alkaline battery. But I use the Energizer Lithium Photo batteries and I have maxed nearly 15 hours of use on a single battery. Since I use mine on hunting or fishing trips, it gets plenty of weather and outdoor use.
The up side:
It's not tiny, but it is small enough. And it's weight is just shy of not noticable. It's simplicity is unmatched. There are no moving parts. So dust and things are not a factor. However, be careful about moister in any form. You can add 128MB Smartmedia card to it to upgrade from 32 to 156. I know the math doesnt work, but for some reason you will only get about 124mb out of your smartmedia card. I chalk it up to the space required for the format. I dunno. None the less the 128MB upgrade makes it a really sweet unit.
Down side:
You lose a little of your storage on the Smartmedia card. Another problem is if you download your music to the memory that is built in, and let's say you have a little space left, you cant use that space after upgrading the memory. So if you use 30 of the 32mb of onboard memory, then you lose the 2mb of space or you put a small lower quality song there. It will not let you borrow space from the card. And when you factor in your preset loss on the smartmedia card, you are losing a small chunk of memory,about 5-6 mb.
Overall I give mine 5 stars. You might consider the newer player, which has 64MB onboard and is only more. Not too oftent you will add 32MB of memory  inthe MP3 world. You can also add a 128MB smartmedia card to increase it to an aprx. 192MB. Hoever, you will probably only have about 185MB that will be useable.
Possible improvements: Allow the two memories to mesh together, as one. Build a unit with am/fm radio, and possibly add a record feature. Also, I would like to see a unit that would use two 128MB smartmedia cards at the same time. Like a unit that has 128MB onboard, and you can add 2 128MB cards to at the same time to crank out 384MB.
