If you Are wondering what a Mp4 player is, it is very simular To an Mp3 Player. They Obviously look different, (Refer to Above Picture) But they have Some Features that will impress you! The Normal mp3 Player will be Able to play Mp3 and Wma files, but an Mp4 Can play Mp1, Mp2, Mp3 and Wma. it can also Play movies and often has things like a colour screen, picture viewer and they are smaller than you would expect!
The first example I've come across, is the postage/Shipping cost. I have come across countless amounts of Cheap Mp4 Players, But The postage/Shipping Cost Is Ridiculous!! For Example, you may Come Across a Mp4 Player for About $19.95, But When You look at the postage cost, it is Something like $65. Don't get fooled like I did!
Another Way that you can be tricked is By the Postage insurance. Always remember to scroll Down And make Sure That There isn't A Large Insurance fee. If its optional thats ok, But Be carefull is its required, you're Going to have To Pay It!!!
Mp4 Players Aren't all bad. I have personally Bought one and They Are Fantastic! I Would Reccomend buying a Nano version. They Have A nice screen, but the wheel is not the same as a Apple version (you click the button's and do not scroll.).
