shRNA system - (Jan/30/2007 )

Hallo,
I would like to ask if anyone from here has ever used the Knockout Single Vector Inducible RNAi System from Clontech? Is it worth working with? Please advise me! We had problem with genomic conditional knockout and we consider other strategies.
Thanks in advance!

well i personnally didn't use it, but these kind of systems are reliableas they hold a strong promoter for control of siRNA transcription.
