The Backbone One doesn't collapse as neatly or completely as the otherwise-bulky Razer Kishi. During playtime however, its fully extended form is pretty svelte.

If your phone's case adds significant volume, you might need to remove it for a nice snug fit inside the Backbone One. That's what makes you a true gamer, right?

Since most humans lack a third arm, be careful when plugging and unplugging your phone from the built-in Lightning port to avoid any accidental damage.
