The instructions that came with mine did say it was weather resistant but recommended keeping it out of "direct" rain/snow. It's clearly made to be used outside,,, I guess the manufacturers are just covering themselves with a generic cover all recommendation. Glad to hear your unit has continued to work out in the open under such weather conditions Harry,,, that's great. I'm really looking forward to setting mine up Monday night and setting the trap for this coon :) If I can manage to get him I will take particular enjoyment in dining on the raccoon stew he's gonna make :)
