Well if you have a CycloDS you have no logical need for another card, but i think the AK2 is cool, sticker will look aweful if you peel it off, be careful of the plastic clips they get white fatigue lines real easy, and if you do take the cart apart part of the silver of the sticker gets stuck to the actel proasic 3 underneath and causes it to lose the shiny layer (like when peeling a 360 warranty sticker while off most of time) it just peels off the color, and it looks bumpy if removed then replaced.
so yeah, be careful if your a nosy git that likes to look inside things,
the cart feels like cheap and unsound in built but its not so fragile it will break if you squeeze it or drop it, but still feels less sturdy than a real DS cart which isn't too good, and when you first handle it you will feel like it will break.
wonder what the original Acekard was like, kinda wish i had gotten into Flashcarding back when i got my DS....
