Set this up on a Hornady LNL Progressive press with 9mm shell plate , Red Anodized threaded fitting wouldn't go down far enough to allow casing to lift internal plastic bushing to activate the micro switch , hit the top of shell plate ! Had to put in lathe and turn down the threaded area like EVERY die manufactured to put a step in it aprox. 3/16" to allow it to fit properly & actually work . Besides that , works like a champ

It is great! It is designed to work on virtually any press with a 7/8-16 die thread regardless of manufacturer.
It is too easy to lose track of what is happening when running a progressive. I think every progressive should have an audible and visual powder alarm.

Great product! Helps prevent squibs. I have one for each caliber I reload.

Easy to install, set up and use. Works very well. Takes up a bit less space on tool head, too.

Outstanding powder check device, easy to set up, great safety addition. Works well with handgun & medium /large bore calibers. As with any powder check device; the only weakness is the inability to function consistently with small bottle neck cartridges, ie, 223. Overall, an excellent product.

This item is doing his job is accurate, 0.2 gr less or more make it sing.
