A lot of business owners want to make big money without thinking twice!  I know that selling fake memory makes more money, WE WILL NEVER DO THIS, I rather choose not be selling in ebay anymore if I have to sell fakes to cheat my buyer.

The cost of 1G/2G is about two thirds of 4G chip.  As for 8G's chip they are even more expensive than 4G.  Everytime we asked for the price quote in China, we will emphasis the fact that we DO NOT WANT UPGRADES, well in Chinese that means fake memory.

How can you tell the MP4 has fake memory?

It will be showing the true memory capacity once you format the MP4.    My supplier in China told me some internet companies uses 1G's to upgrade to 4G's or even 8G's.  Some uses 512 to upgrade to 2G's. or 4G's

How to format the MP4?

Please refer to my other review for data corruption.
