I used the vieo down below as a guide, as I am sur a lot of people have. But I noticed that you could see the little hole in the case where he used the compass point to sart the clips. I check out the case and ended up using a guitar pick to sart on the left hand side of the empty microsd slot. There is a clip right the and it popped easily, and the whole side popped with it down to the left corner. The corners are a little stiff but I just worked gently from that corner clockwise. It took about 5 minutes to have it open and my test card inside. I tested both my 32GB Class 4 and my 16GB Class 6 with CFW GingerLF EVO and both worked perfect. I ended up using the 16GB since it was a little faster.
