Need opinions about Pioneer DDJ-T1 with Traktor

Guys I have the Gemini G4V with Traktor. I love Traktor but the Gemini is not 100% compatible to Traktor or you need to do your own setting but the Gemini’s logic is difficuilt to understand.

I found one DDJ-S1 used for 350€ and as I am concerned, this controller is 100% made for Traktor. I use version 2.10.013.

Does anyone have experiences with this controller?
Does it have loop roll for example?
