Yea, I've used mine once at field 51 with disastrous results. I forgot how low I actually needed to be in order to blend in. This resulted in me being eliminated a lot due to the no break necessary rule for Ghillie suits. If you're going to use it, stay low, stay quiet and don't move. Hydration is an absolute must! Drink tons of water at every opportunity, I actually carry a camel pack underneath my suit so I can drink while I stay in place.
