Anyone taken ISC2 CISSP bootcamp training?

Hello Guys, I have been wondering if anyone here has taken the bootcamp from ISC2 provided seminars or instructors? On their site, there is a third party institute called trainingcamp.com which seems to be the only authorized third party institute and they get instructors from ISC2.
Is there anyone whose taken training or planning to take one from ISC2? Any guidance is appreciated. Thanks.
