Customer Comments

In my office meetings we would discuss how we sometimes miss things at the office and the DVD helped to see how easy this can happen.

I used it in a safety training class to demonstrate the fact that if you are so focused on one task that you can miss obvious hazards/situations.

The gorilla clip is very effective in getting people to realize that there are 800 pound gorillas (huge improvement opportunities) all around us but we can't see them because we are too focused on the wrong things.
