No. Tried many signs, none worked until this one.
Found on web - wealthy gun collector, which I am not, had 2 or 3 thefts as his signs too were ignored. He devised this one & thefts stopped. It is very effective.
It is Also true - we have our own gun range & shoot any time, & I also practice shooting from our front deck.
Love it! Do you still have a link on where to buy one?
