I use it for ten months. I love the possibility to use it in combination with any computer, making a USB1 sufficient to transfer (in one or other of two directions) of mp3. The battery life is very good, and the battery is user replaceable ... The controls are a bit small (this is the price of its small size).
I bought this unit to replace an ipod 20 G slammed twice in one year (a replacement warranty). The Archos is smaller, more reliable, usable without installation ... and costs less!
The price / quality ratio is excellent: the quality is very good and moderately priced.
I would do without hesitation that choice (I also bought several for my kids).
