I've had another AGPTEK MP3 player before, and they've gotten much better over time. The user interface used to be pretty guess-and-check, where it was anyone's guess how to actually navigate through menus and buttons were often the reverse of what they logically should have been, but the current UI is almost intuitive and pretty easy to use. I like it.
Pros: Price, obviously. It's a good MP3 player for the money. Construction: Well built. Everything fits, it's a clean design, no sharp edges, fits well in pocket when out or exercising. Can survive a hard drop or two. User Interface: The UI is simple and easy to use. It's also easy to load files to it, just like a thumb drive - no software like iTunes needed.
Cons: Sound quality: It's not the best. This is the biggest drawback. It's decent using can-type headphones, but using earbuds it sounds tinny and awful compared to more expensive products. 'Video support' - description says it supports video, and it has a menu for it, but the only video type is supports is MJPEG. Never heard of it? No one has. It's basically an obscure, animated GIF type format that no one uses, so it basically does not support video at all.
So, in short, I wish I hadn't put my iPod nano through the wash, but this is a pretty decent replacement for the price :)
