How to use: First, make sure you have the DX Gamer Driver. Then, simply insert the Taddle Legacy Gashat into the driver to start the exciting Kamen Rider Ex - Aid experience. Note: The DX Gamer Driver is sold separately, so you'll need to get it if you don't have one. Maintenance: Keep the Gashat in a dry and clean place. Avoid exposing it to extreme heat or cold. If it gets dirty, you can gently wipe it with a soft cloth.
