mine arrived on the 27th december and i have had a bit of time to play with it
what it will do is automatically back up your CF card or SD card as soon as it is inserted with no user interaction
it will display RAW / JPG files on your tv via hdmi and also play back and video files, unfortunately if your video files are 4k and your tv is only 1080p it will not downscale the 4k video footage to suite your 1080p tv and refuses to play them
what it will do is play back m2ts video which is nice because my slideshows rendered to blue ray play fine as m2ts format files
with the very small bit of experimenting i have done it looks like it will backup and display any JPG images regardless of who makes the camera it came from i tried a few from a nikon D3 and it was fine but it will not backup the raw files from the same camera
i have to say it's not the fastest thing when backing your CF cards up to the device i would say it's quite slow but it does get there eventually
as far as NFC and wireless is concerned iv'e not tried it with anything yet so no idea how it performs or what it will or wont do where that's concerned
i have found that if i want to rename an album i need to do this from my pc via network connection and going to properties of the album i want to rename
there might be a way of doing this via the boxes own interface but i havn't found it yet
there are firmware updates available that is supposed to give better compatibility with other makes of cameras / phones but i havn't tried another make yet so can't really comment on what is or isn't compatible
the input voltage is 7.5 volts which is a pity i was hoping it would be 5 or 12 volts making it easier for using as a portable device but all is not lost if using it in a car or from a 12 volt source is an option using a variable voltage DC to DC 12 volt adaptor like one of these

unfortunately Maplin don't stock this item any more but i'm sure a bit of googling will find a similar product
my intentions is to use it in the caravan while we are away as a backup for my CF cards and for that purpose it will do nicely with the added bonus of being able to display the images on the tv, it saves me lugging a laptop to do pretty much the same thing
