IMHO the electronic powder check is a must safety component when reloading on a progressive press. Even with the alarm, I also watch the magnet index into position at each press stroked as part of my loading cadence. This is an absolutely key tool to prevent squibs or overcharged loads.

This is a well build product. It has a wide range of sensitivity, meaning you can adjust it down to a few grams of gun powder or set it just about where you need an alarm. We purchased 3 of these units. We have them set for over charge condition. Our units alarm at .5 grams of over charge and do a great job for us. We only make pistol ammunition. Great product.

To start I have not used this product yet. I am currently running the mr bullet feeder in that a spot but I am thinking about trying the seater crimper die to open up a spot for it. As far as first impressions go, looks ro be well made and an improvement over the Dillon checker.

After reloading for many years, I recently made the transition to a progressive press. I primarily reload 9x19 and selected a Mark 7 Apex 10 press. The DAA Powder Check 2.0 is installed immediately following the powder drop and before the bullet drop. The DAA Powder Check 2.0 installed and adjusted easily.

The ONLY issue I have with the Powder Check 2.0 is that it did create a significant mess on the shellplate after 200 to 300 rounds. The problem is not caused by static electricity, but rather the airflow caused by the powder check brass plunger displacing the air inside the case during the stroke. The problem is likely more significant when loading 9mm with fine powders (my case). Also, the fact that the brass plunger enters the case at the point of the stroke when the tool head is moving most rapidly doesn't help.
After much weeping and gnashing of teeth, I was able to mitigate the issue substantially. After setting the powder check die depth correctly, I purposely inserted a case that was loaded with powder 1 grain lighter than my normal charge and cycled the toolhead down. With the toolhead down, I put a zip tie around the steel shaft at the top of the die so that the plunger could not drop any lower during operation. I then removed the light loaded case, and replaced it with a correctly charged case to complete the setup (magnet position). Basically, I just reduced the speed that the brass plunger is moving when it enters the case now.
Doing this, the powder mess was almost completely eliminated and the powder check still identifies incorrect loads.
My initial thought was to give a lower review, but I believe the problem I encountered was due to the combination of the case dimensions, type of powder, dimensions of the brass plunger, and speed of the press stroke in my circumstance.
It's a very innovative product that works quite well in most circumstances. 4 stars and I will purchase the DAA powder check again if the need arises.

Thought I was only going to use on 38 Special reloading because of tall, small case which is difficult to see powder levels. But because it is so easy to setup, I use for everything. The light and buzzer give you peace of mind.

Very good quality and functional, and it fits my new Lee six pack pro just fin !!!
