Idk, my Logitech K400 was $30. It may not have backlights but it has a trackpad with discrete buttons, a surprisingly useful left click button above the escape key and I've only changed the batteries maybe twice in 5 years. 

It's a pretty fantastic couch keyboard for 1/10 of that price. It even works fine on slower paced games. Used it to play Disco Elysium a while back.

Edit: Somebody posted the actual listing by Corsair further down and msrp is $100. It actually looks like a pretty solid upgrade from the K400 for that price if you're looking to do a bit of couch gaming with it.

Looked into the k400. Great specs and love the layout. Unfortunately the lack of backlit keys is a nonstarter for me. IMO living room computing is only doable if it works in the dark (movies, nighttime gaming, etc).
