Summary: I had one heck of a time just getting my Slacker to work, after that the power button the device was constantly acting up. It would be very unresponsive from time to time and caused me to drop my device, inflicting cosmetic damage. I had to get it replaced. The new one was the same way. For a whole week I couldn't use the device simply because I couldn't turn it on. The screen would light up when I plugged it in but that was it. When the device does work it works well.
Summary: I recently returned my second unit as it completely stopped working as did the first. At first I had lots of stability issues including: - player stops after playing some number of songs and will not restart. it will either just stay blank or show starting up for a few seconds and then going blank again. It will repeat this cycle if it is plugged into USB. It seems pretty random about how long this will last before it works again.
Summary: I've had this product (8 gig) since April. Originally I was quite geeked about it, but as time goes on and Slacker hasn't released accessories and has not fixed major bugs in the design, I've lost my enthusiasm. They haven't released a bug fix update since the beginning of May, and I've become tired of the lock ups and difficult user interface, especially now with over 400 songs loaded on it.
