This size & form factor works great when recording DSLR vids on a tripod.
I have the Tascam DR-70D, which looks similar, albeit a little shorter in depth (4 channel).
Too bad the slick bluetooth Control app is iOS only.
The 1K price tag might be a turnoff, particularly when 8 channels might be overkill for what this would typically be used for - a field recorder.
Most standalone digital recorders with more options are 1/3 to 1/2 the price, but the F8 is nice due to it's size.
