I know the name but don't know anyone certified by them so I checked out their site.
To be polite I'll say they are a cheap imitation of Pavel's RKC. In the videos their instructors, to be honest, have horrible technique and I would advise you spend your money on someone better.
I've done a number of certs/seminars and know who's who in the KB scene in the U.S. and in my opinion Steve Cotter & Ken Blackburn's
International Kettlebell and Fitness Federation is at the top of the heap.
The
American Kettlebell Club is up there too, but is based more on kettlebell sport (until now), though there is no better group to learn technique from.
The RKC also has many good points, but seems to have declined. Very expensive as well.
If you want more info feel free to PM me.
