I had bought 2 of these alarms from Marc the site owner. One a couple years ago, the other about 5 years back. Great products. Use them all the time.
I do allot of backpack or solo hunts and usually have 1 set up around my tent and/or one in my pack that I set up when I am dressing game by myself. (Gave me a great sense of security recently while field dressing a elk after shooting light in Griz country by myself).
In any case, on a recent hunt I managed to break one of the trigger sticks and loose the other.
Made an inquiry to Pac Alarm and with a couple days the owner asked for a mailing adress and replacement items are now on the way, free of charge.
Anyway, great piece of gear and first class product support.
