A review of the Rikomagic MK802 III, an Android 4.1 MiniPC with a dual-core RK3066 CPU and quad-core GPU, tested as a budget HTPC and casual gaming device.
It has a MicroSD slot (up to 32gb), HDMI output, USB OTG port and it is powered by a Micro USB Port. 
Bundled cables: Short HDMI extender, Micro USB to USB (Power Cable). 
Size : 90mmx40mmx13mm 
The Rikomagic MK802 III is a great Android MiniPC, the interface is smooth and nice, and it works great as a Low End HTPC. It still has a lot to improve like CPU and WiFi performance but it is a great upgrade for your TV.
Using BsPlayer i was able to watch 480p MKV videos over WiFi and some of the 720p MKV videos but most of the 720p had an issue with Audio-Video Sync - obvious lack of CPU.
Another thing you can do with the MK802 III is play online games. It has a very nice gaming performance and most of the games run just fine without any problem using it’s Quad Core GPU AMD Z430.
I would recommend placing it close to your Router/Access Point for best performance.
Pros: - It responds very well with Youtube and other 1080p streaming media. - Android 4.1 OS - multi-language support. - Nice built in remote - Android Smartphone as a remote controller over WiFi. - Price - about 60$ including world wide shipment. - Quad Core GPU for gaming.
Cons: - Can’t play a 720p MKV or above. - Weak WiFi reception - I had to place a wireless repeater very close to the MK802 III for usable LAN speed. - UPDATED - full screen button restored after update. No “fulllscreen” button in Youtube application - Tubemate / Web works fine. - Lack of CPU performance - Quad Core would be a great improvement.
