They don't last forever, replacement kits are available with free shipping. Kit includes RF Mini, Remote, Inner Heat Shrink, and outer Heat Shrink. All you will need is some electrical tape, a sharp knife, and a med temp. heat gun to replace your controller when it finally fails. The miniatures do not last near as long as the big white box ones.$19.99 and I ship you the kit. Get the stik back to me and I fix it for $20 parts included. Shipping not included.
