Purchased four of the Gen 4 Trip Alarms with bear deterrent shells and a .22 power load adapter. These are high quality devices made in the USA, and are NOT poorly made units with substandard machining or components originating partially or wholly from overseas. In addition, there are no gimmicky trip plates, unnecessary handles or cheap chromed parts. It is a shame that overseas manufacturers have once again found a quality American made item to knock off. There is an old proverb: "Buy the best, only cry once." After researching various options, I found that the FITHOPS trim alarms checked all the boxes that mean something to me.
