Reply to Kontrol S4mk2 -- Reliable for gigging ?

So i've narrowed it down to the S4mk2 for smaller gigs where i dont wanna lug around my TA10/Xone/X1's and Maschine.

I am used to NI gear, controller editor etc and am sure the S4 mk2 has tight integration with Traktor Pro, however i am new to the all-in-one game and have doubts about reliability as if one part fails, it all comes crashing down.

Guys if u have gigged regularly with an S4 mk2 ( or other 4 chan controller ), please advise as i will soon drop hard earned cash on one.....

Thanks
