The Streaming Stick plugs directly into the HDMI port of your HDTV and is teeny tiny enough to be used on wall-mounted TVs as well.
It means you can watch on-demand films, TV shows and music videos on your television using a Wi-Fi connection, as well as being able to play videos and music from a smartphone or tablet.
You can use your phone or slate to control the stick as well, thanks to the Roku Android and iOS app - but it does come with a remote control too so you can use that if you prefer.
As well as Netflix, YouTube, Vevo, Spotify and HBO Go, Roku offers over 1,2000 channels including movies, TV, music, news, sports and free programming. It's all delivered to your screen at 1080p HD.
There's also social network connectivity through Facebook, Flickr, Vimeo and more.
If you're thinking this all sounds very similar to the Chromecast, then you'd be right. It seems the TV dongle stick wars are only getting thicker.
US customers can pre-order the Roku Streaming Stick online from Amazon, Best Buy, Target, Walmart and Roku, with an expected arrival in April.
It'll set you back around $49.99 (CAD$59.99/about AU$55), and there's no word yet on an Australian release.
