MK808B Pro Android TV Stick Mini Review

MK808B PRO is the first Amlogic S905 TV stick readily available for sale, and GeekBuying sent me a sample for review. I’ve already checked out the hardware, and the lack of heatsink is a worry, so we’ll see how it performs in this mini review, where I’ll focus mainly on potential pitfalls, rather than do a throrough review as usual, since I’ve already tested so many Android TV boxes powered by Amlogic S905 processor First Boot, Settings, and First Impressions I’ve connected MINIX NEO A2 Lite air mouse RF dongle to the USB port, and Tronsmart Mars G01 wireless gamepad dongle to the mini USB port via the provided USB OTG adapter, and the provided HDMI cable to the AUX port of my AV receiver and nothing else, except the power adapter to the other mini USB port. Boot time typically takes about one minute that it’s not a speed […]

Zidoo X1 II 4K Android TV Box (Rockchip RK3229) Review

After skipping MXQ-4K TV box review due to severe issues with video playback, Zidoo X1 II is actually the first device powered by Rockchip RK3229 processor that I’ve fully tested. I’ve already taken pictures of the box, and opened it up to check the board in Zidoo X1 II unboxing and teardown post, and confirmed 4K videos could play pretty well from my USB hard drive using Zidoo Media Center after disabling Media Scanner process. So today, I’ll review other parts of the firmware, as well as video playback with ZDMC 16.0, Zidoo’s fork of Kodi 16.0. First Boot, Settings and First Impressions The device only has two USB ports, and I used one for a USB hard drive, and the other for RF dongles for MINIX NEO A2 Lite air mouse, a USB keyboard, and the RF dongle for Tronsmart Mars G01 gamepad via a USB hub. I also […]
