Reply to Novation ZeRO SL Mk II, anyone used it?

I already own a Denon DN-SC2000 and I'm looking for a midi controller to control effects and decks 3&4 in Traktor. the Zero SL MkII will probably to do the job for me, however there seems to be a lack of reviews on the internet.
has anyone owned or used one them?
