I nearly bought one of these a minute ago! Lucky I didn't! I'd love a weteck hub but at around £75 not including shipping I just can't afford it. Will wait and see if any UK seller starts selling the revised version of the Beelink over the next few months. Of course perhaps the reason the one I was looking at was only £33 with shipping was because it's older stock?
Oh and one question to those that have a miniMXIII, does it handle 29.976fps out of the box or will this only work with a custom ROM such as K's. Apparently the WeTek does 29.976fps as standard which is one good reason to consider it. wrxtasy's review of the hub here: WeTek Hub - 24p HD Netflix - HD Kodi Audio - 10bit HEVC - Lollipop - 4K
Well honestly i can't tell if the low price was due to "the old revision" but probably no. Of course i cannot assure also that in the next few months there will be a revision of that particular box "miniMXIII" what i've said are only speculations (as we know these Chinese manufacturers i'm expecting new boxes with different names as MiniMXV or something similar). For sure the Mini mx, Odroid C2 and MiniMXIII have problems now with some 4k Hevc main10 at 50fps. If you are going to wait and not need to buy a box soon (or yes not going to buy the hub) well you might put an eye on the new boxes with Amlogic s905X that as confirmed by cnxlinux don't have the 4k issue: but new processor means times to get some LibreELEC port.
