I'm unsure if this is a decent Android box or not, but for $49.95 it might be alright. The Jaycar site gives the following information:
This advanced Android media player allows you to browse the web, run Android Games and Apps, or watch your favourite movies in 4K or 1080p resolution on your HDTV. It connects to the Internet via Wi-Fi or wired network, and to your TV using HDMI. A digital audio output allows you to connect to an amplifier or active speakers. The Android 7.1 Nougat operating system allows you to customise the player with your own choice of Android Apps, from Netflix to playing YouTube clips. When you are not streaming content from the Internet or the internal 8GB of storage, you can watch media from your USB Hard drive, flash drive or SD memory card. All the standard audio, photo and video formats are supported. Includes infrared remote control, HDMI cable and mains power adaptor.

EDIT: For those whinging that I'm not following the posting rules, here's the rule in question:
Summarise briefly why it is a bargain - why did you buy it or consider it worth sharing? How does the price compare to elsewhere? Can you comment from personal experience on the quality of the product?
Since you want an answer, other currently available media players are more expensive than this one, which is also available through an Australian retailer if you're not keen on buying cheap electronics on eBay. I have not tried it, so cannot comment on its quality compared to name brand media centres or similarly spec'd devices.
There you go, issue resolved. If you think otherwise, I refer you to this rule:
REPORT any problems to a MODERATOR.
And this one:
BE respectful to others.
/EDIT
It looks like their normal price.
Why is it a bargain ?
