we say clones but on ebay there are meny different designs some look like nanos some not
TBH do not buy from ebay or any auction site, ask here for genuine stores
if u want a nano clone look to
Digital Kingz Wholesale Cell phones, Mp3 players, Mp4 Players, Mp5 player & ipods, Onda, Ramos, Teclast, Meizu, Apple, TMSON, CycoTechUSA wholesale Camcorders, Cameras & other great electronics. and to their nano exact players, they are a proper store in the US
basically take this query and paste it into ebays search
"32GB mp4 player -sansa -cowon -apple -sony"
everyone of those players will be fake as will they be if using 16GB like so
16GB mp4 player -sansa -cowon -apple -sony -ramos -onda -ainol -creative
just about all will be fake
memory is expensive, especially if you want a 32GB player, sellers know people want more memory, this is the reason they do it, there is no way you can get a gen 32GB player for the prices people are paying on ebay for these faked out players
