The all new PROBOX 2 Air Plus is as fast as it says on the site. After testing for a couple of days, it runs smoothly and video quality is very nice. The PROBOX 2 Air Plus has GB DDR4 RAM, 32GB eMMC flash memory and up to 1Gbps Ethernet. It can even show up to 4K video with the all-new 10-bit video and HDR. A lot of weird words, I know, but it just means it’s a good device.
