"My daughter has a learning disability and so can't turn her TV to the correct Channel! She can now ask her google to watch anything on Netflix or Amazon! Fabulous!"

Google steps into the world of 4K streaming with the Chromecast Ultra. Just like the regular Chromecast, this little HDMI dongle lets you watch streaming content on your TV from services like Hulu, Netflix, and YouTube, but it supports 4K video in HDR. It's the most affordable 4K media streamer on the market, but at $69 it's nearly twice the price of the 1080p model and comes very close in price to other 4K media hubs that don't rely entirely on another device for playback, including our top pick, the Roku Premiere+. DesignThe Chromecast Ultra is a 2.3-inch-wide, half-inch-thick tapered black plastic disc just a hair larger than the regular model. Its aesthetics are sleeker and more streamlined than the Chromecast or Chromecast Audio, in the form of a simple glossy black plastic body with a small matte G for Google engraved on it. A three-inch cable extends from the device and terminates in an HDMI connector. A micro USB port sits on the opposite side of the disc from the HDMI ca...

Google's 4K-capable Chromecast Ultra is the least expensive UHD media streamer available, but you still need a smartphone, tablet, or computer to control it.

Ethernet port for reliable 4K streaming; Relatively inexpensive for a 4K media streamer

Requires a smartphone, tablet, or PC; Almost twice the price of the 1080p Chromecast

Streaming from your phone in 4K

Excellent cast quality, 4K HDR10 and Dolby Vision support, Simple setup

Needs more 4K support, Amazon and Apple missing, Slightly expensive

Casting, Google Cast or Chromecast represents one of the greatest steps in recent consumer technology. The ability to fling content from a phone or mobile device to a big-screen TV and control it from the palm of your hand is simple, but great.

Ultra HD; HDR and Dolby Vision support; Ethernet connection; simple; fast; easy to use; affordable

Your smart TV probably offers all these features already; needs a consistent method for confirming the quality you're viewing

If you have a 4K TV and a Netflix subscription, the Chromecast Ultra is worth the £69 asking price. The fact it is so easy to use and works best with the Google Home app means you can easily throw it in a bag and use it on different TVs wherever you are, as your phone or tablet carries your...

Google's Chromecast technology has pretty much become ubiquitous since we reviewed the original media bridge back in 2013 . Chromecast built-in is now a common inclusion in many smart TVs, soundbars, media players, and AV receivers.

This product has transformed my old TV into a smart TV. Great for you tube tutorials. Easy to use. I recommend this product.

Plugs straight into HDMI on the TV and it's handy to have if you don't have plain tv service.

If I had known I had to cast everything from my phone I would have just bought another Roku. I am using it for youtubetv and their app is very clunky on the chromecast and MUCH bettter on Roku. FireTV would be even better if they weren't in a feud with google and youtubetv worked on it.

More stable I would say than the original chromecast. I had some intention to buy this for better picture and 4K ability but this actually has a better connection to my wifi than the original chromecast 2nd gen. For all of those who keep loosing signal this could be the answer.
