There are a lot of companies that are trying to replicate the Chromecast magic. Just a few days ago, the latest was Walmart who outed its own VUDU Spark HDMI dongle to go with its movie streaming service. Now there's a new contender and it's a slightly odd one. The Rikomagic V5 TV strangely looks bulky compared to other dongles that try to take on the Chromecast. But that added mass on the end suddenly makes sense when you discover that it has an Ethernet port on that side.
