Recently bought a gun that ended up having light primer strikes on one side. Gunsmith lengthened the firing pin. Shot Winchester AA and everything was fine. Then I tried Herters, my reloads, Remington, Fiocchi, and Federal. Several of the factory loads still did not fire. Gunsmith says he had no problem shooting this gun but only uses AAs...I returned the gun to the seller for a refund.

Sounds like a device to extract money from the gullible .Pointless in my opinion as there are several ways to test the efficiency of strikers with no cost , just a little practical knowledge and common sense .

Gunman-thanks for your experience with the device. Would you mind telling me how much you paid for yours.

A capped case , a pound coin , a block of hardwood , a penny is all you need to test the efficiency of any double gun striker. When you have eliminated all other possible reasons for a misfire . Broken worn mainsprings , damaged return springs ,worn or broken strikers /fire pins , gun not cocking fully or something preventing the hammer from falling correctly , dirt etc. Hard primers are the most common fault . Basically what you have in your pocket or on your bench .

when reusing a spent shell, and inserting new primer in it, it may work, but it may not. sometimes the head becomes concave from repeated use since there is no back pressure of firing an actual load, and can give false readings, such as not firing even if there is sufficient firing pin protrusion and energy to the firing pin.
That is the benefit of the Brownells test kit. I have had one for 40 years.
other methods work. I choose this one.

Thanks Brian, that's the direction I'm going.

Gunman, spot on as usual.
