After I read the entire booklet, which, I do agree, was a little difficult to read because it must have been translated, I could not get mp4's to transfer. The box says its a mp4 player, but in the back of the book, it says its only compatible with mp1, mp2,mp3, wma,wmv, asf, and wav. I could not convert my iTunes to any of these formats. The buttons seem cheaply made, I'm afraid I'm going to break them when I "long press menu button", (as the instruction booklet says to do, they meant holding down the menu button) The sound quality of the headphones aren't that great. You can't use your own headphones because the plug-in part is super tiny. I tried the voice recorder part, but couldn't get what i recorded to play back. It turns off quickly. The battery lasts for 2 hrs max. The screen, however, is pretty crisp, and I enjoyed the little video that comes loaded. In the end, I wouldn't get this again. Since I already opened it, it wouldn't be worth it to return it. I'm just going to give it to my 5 yr old. In closing, what do I need a radio for if I have mp3's to listen to? Save your money and spring for the iPod.
