This powder checker is great. Every time it alerts the powder amount in the case is incorrect. I have not had a false alert using this checker.

These are great. I have three of them now. It's real nice no hearing the alarm when you skip a case!

Easy to set up, works great. I was waiting on the seating/camp die so I could open up one of my stations on my 650!

This powder check is amazingly effective. We run an ammo manufacturing shop running 2000 rounds per day. Thank you Double Alpha for this great product.

Best powder checker that I’ve ever used. Highly recommend.

Purchased two of these items, works GREAT, on first run had a media pin stuck in primer hole, the new powder checker caught the problem. Takes a little bit to get set up, but once set runs flawless . Will purchase again for my other presses.
