interadd , that's good! Some people in here only managed to get a purchase price refund, return postage was at their own cost.
Just a note of caution, there are no legitimate 4GB nano-clone players around, especially on eBay. Mostly are hacked, even the advertised 1GB and 2GB models are hacked. What i'll suggest is purchasing your next player from reputable sources like
uxcell.com. Or if you are after 4GB models in eBay, try the Meizu branded players. They are slightly more expensive, but definitely 4GB is 4GB.
Else, if you buy another similiar "4GB" player like your previous buy. You might not be so lucky as to get a full refund, if the player turns out to be hacked again.
