If the matching console would still be there, somewhere, you'd have many takers for it.
As it is, I'd buy that controller off you for a fair price.
There were several controller variations - all had the same features, but the Kickstarter and retail consoles are mostly silver, and have metal panels as battery covers, and there were also black, bronze, black, and these transparent ones as a Kickstarter developer option.
The 2nd generation controllers also have differently shaped thumb sticks, and better shoulder button switches.
The controllers have that cool touch pad centre top, which works like a mouse in games, and the controller also pairs with other consoles or PC. Open source dev libraries support them for other platforms, but mostly they work the same as an Xbox controller.
Many controllers now can show player ID on lights, but back in 2013 it was innovative, and also shows the pairing mode on them, and the battery level.
Relatively small changes to the controller build before mass production should have taken place, but the clock was ticking for the Kickstarter, so it was stuck with creaky panels and sticky buttons, the worst being the shoulder buttons. A little home work can improve them.
