Just took my DSLR-Devices microjib for a shoot last week and here are my thoughts:
Plus Point:
Weight: compared to my Steaditracker PhotoCrane, the DD micro jib is lighter for sure.
Set up time: Very fast just like the demo video.
sturdiness: Will take even the heaviest DSLR
Minus Point:
Length: A good 1.5 feet shorter then the PhotoCrane, I couldn't get very low perspective when my tripod is at full height.
Tilt control: Nightmare controlling the tilt ; Can tip the whole jib over if the you tilt too low. Very limited angle.
Safety: Very low safety score for the DD due to lack of anti-swivel pin or hole at the camera mount plate and the tripod attachment plate.
I strongly recommend boring your own holes before taking the jib out.
Operability: unlike the Photocrane, it is difficult to control the tilt on the DD micro jib when you are hand-holding the camera. As with most parallelogram design, the entire weight of the jib is pivoted at the tripod head. Got my finger almost crushed between the two parallel bars when tilting the camera.
Verdict: Although lighter and faster to set up, DD micro jib is not as safe nor as easy to use as the steaditracker PhotoCrane. A shame as the DD cost a lot more. When you take the counterweight into consideration, the weight savings over the photo crane is not much percentage wise. The parallelogram design of the DD is not as stable as the pulley cable relay tilt control of the photo crane.
