In the event that you misplace your slick little, manageable only with baby hands Chromecast with Google TV remote, Google has replacements for you.
The new Voice Remote for Chromecast With Google TV (official name) is currently listed for $19.99 in all three colors.
Although the remote can only be purchased separately from the new Chromecast, Google made a wise choice by making them available. Aside from the possibility of losing one, you might think about purchasing one if you prefer a different color than the one that came with your dongle.
You can now purchase a blue remote if you purchased a white one or a little sister remote if you purchased a blue one.
