I'm impressed with my experiences of this flashcart so far, even though it's a bit pricey. Compared to the original model, it's larger and has a more premium feel to it.
The micro SD card does still need to be pushed in place, as it does not use a springloaded mechanism. You also need to hit a physical switch to change it from GBA to the DS dual slot 2 mode.
Overall I'm happy with my purchase and I look forward to revisiting the Gen 3 Pokemon games on here.
