Bought these for a recent remake of a gameboy DMG-101. purchased in white to match my aesthetic.
I found the membranes to be too "soft", especially with the directional pad membrane. I will often have multiple inputs at once now, making tight game play impossible. Usable for rpg's or slower games, but not for action or platform games. Nothing worse than crouching when trying to run straight ahead and leading to death.
I do not know if the other colors are like this, but the white ones were not very good.
