I still use my previous AGPtek Mp3 player. I use it for Audio books almost exclusively. It is great for Audio books, it remembers it's place- which is not as common as I would like to think.
The new one I can't say much about yet except I like the weight and heft of it. It seems solidly made. And it does what it claims to.. It plays FLAC files well! On the rare occasions when I Jam non-books it sounds Great! I also wish to say that I like the wheel- it makes selecting easy- The detail I found least-easily was the The wheel pushes in that is to say it is the main selector switch. One spins it then clicks it. I didn't discover that for a while. But, knowing about it now I like the innovative nature of the feature.
I plan to come back to this review as I learn more about this device.
