I've been playing non-stop with this thing since I got it home yesterday and didn't get to bed untill 3am. Now apart from it not working with my Dune HD D1 (Which I'm extremely annoyed about) its a gem of a device.
At first I must admit I was a little underwhelmed after reading all the great reviews and happy users I was struggling to see what all the fuss was about. But now I have had a good play on many sources its a device that I would struggle to depart with.
The effect is very subtle and TBH you may think its turned off when its not, But when you do turn it off you realise how much it adds to the image. They is no doubt, The better the image the better the darbee makes it look.
Its very good at bringing out background detail, Trees, Window frames, structures and on close up shots it adds a lot of detail to faces, It brings out skin pores, hair, eyelashes, eye browse etc. It seems to do this by adding contrast to the outline of detail.
If you watch a poor HD source or a movie with lots of film grain and have the Darbee whacked up above 70% it does make a mess of the picture and seems to try and add detail to the grain to make it more grainy.
I found the Darbee most effective on kids animation blu rays, UP, Shrek, Toy Story etc, It adds an amazing amount of detail and when you turn it off the image looks so soft and out of focus.
I currently have it set on HD around 65%, Having it on Full Pop mode seems to darken the picture too much by adding a lot of dark shadows around things like windows, doors, cheek bones etc.
Overall all I like it more and more every time I turn it off its just a shame that it doesn't work with my Dune HD player. Not allowing users to update the firmware is ridiculous and the design of the unit with the HDMI connections on the side instead in the back is also baffling.
