In Star Wars - Episode IV: A New Hope, Luke uses a training remote found onboard the Millennium Falcon as part of his lightsaber training. A picture on the Wookieepedia page for "Training Remotes" is captioned "Han Solo's training remote":
The remote remained aboard the ship for decades afterwards, and was discovered much later by Finn in The Force Awakens, while he is rooting around in equipment boxes.
I don't understand why a non-Force-user would have one of these devices around - it seems to be designed for use by Jedi learning to deflect blasters, and appears to have very little usefulness to anyone else.
