They're cool. And they work for false controls like the original

Seamlessly fit the controls in the different parts

Perfect, they adapt to any joycon, even differently from the original ones, good construction though not the best material, very comfortable, they arrived in about 3 weeks in Mexico City with normal shipping, the box came badly battered but as they have protection, the grips came in perfect condition. Very happy with this purchase!

Perfect for use with non-original joycons that don't fit in the original
