poorly design product:
the first one, the two controller are join together so if it want to play two play, they will have hard time controlling .
the second one , is the person fire a bullet, it will most likely to hit himself
the good designs: the first product is bendable so it can put it in some places in the devise that the space is small so it can stuff this product in
the second product is a mac book air . it is small and thin .so it takes up a little space
