I took this course last weekend and really enjoyed it. My experience was the same as lawaia posted in February. Darin is and his instructors are fist class with a wealth of experience and knowledge.
As a long time shooter (over 30 years), but with no formal training, I learned an amazing amount of information, and was exposed to what I really don't know and the skills I need to improve.
They gave me a new perspective on personal defense tactics, strategies and preperation. Drills to stay off the X (movement), strong side/weak side, realoading, transitioning between weapons and around cover all made it a positive learning experience.
I will certainly be back for another class soon.
