6-Pack Perimeter Trip Alarm, 12 Gauge, Bear Deterrent, Black

These failed every time. Tried three of the six with multiple shells. The primer is being stuck just fine right in the middle. The spring does not appear to be strong enough for the very blunt strike pin. Grinding this to a point would probably fix this.Also the pull pin is easily thrown into the weeds as it's an open 3/4 loop. This is another poor decision. A piece of shrink wrap over the loop would stop that if you want to modify these.All in all bad execution on a basic workable design. I am going to modify them as this is not hard having the correct tools.

This is a very basic product. Not a lot to do, so that it is setup. I setup the product and the spring on the firing pin is not strong enough to activate the 12 gauge blank. I will order from another company.

firing pin is too wide and will not fire a 12 ga blank or 209 primer , needs to be thinned down and rounded off .
