This seems to be better built than the Frankford Arsenal vibrating primer tool. It works about the same, but the DAA product has a little more clearance between the two plastic plates. When vibrating, it has a tendency to flip over some of the small pistol primers I was using. That can be mitigated by paying attention when pressing the vibrate button, but it is slightly annoying.

I wish I had bought one of these 35 years ago, even before they were invented. If you use primer tubes GET ONE OF THESE. Quality made, very nice materials and best thing is it WORKS GREAT EVERY TIME. Go ahead and get the DAA primer tubes and DAA Primer tube rack, you will want and use them.

I was tired of my fingers cramping up, but wasn't sure this was worth $82. However, I'm glad I took the chance, and spent the money, and now I cannot believe I loaded over 2500 primers without this. It works great with Federal small pistol primers.

Like all primer flip trays, I end up with 2 to 4 that I have to flip over manually, but once you have all the primers oriented this loads the DAA pickup tubes quickly. I load 500 rounds at a time, and night before I will load 5 tubes. I can get those 5 tubes loaded in about the same amount of time it would take me to load 1 tube using the old "hunt and peck" method, and those five tubes are loaded without my fingers cramping up.

I will suggest getting some 7mm end caps, so you don't accidentally spill the primers, after you load the tubes.

Been using mine for 4 years or so. Once you get the feel for it, it’s super reliable and fast. I am not even considering anything else to “upgrade” to at this time, considering how well this works.

I have both Dillon and DAA primer tubes for small pistol primers. The DAA tubes loaded flawlessly, while the Dillon's hung up now and again. I measured the inside diameter of the tubes and found that the DAA tubes had an interior diameter at the feed end on 4.67mm, while the Dillons were closer to 4.62mm. A few quick little passes with a round file later, and the Dillon tubes loaded flawlessly. Not sure if the file just removed some burrs or the least bit of material, but that 0.05mm difference made the Primafill work perfectly. YMMV.

I do wish that the lid fit a little closer so that primers couldn't flip over with the lid in place. I've had to stop a couple of times when I have seen a primer flip over in the tray.

However, overall, a great product that performs very well.

Tech support helped with some technique suggestions but here are the issues I experienced.
1. The flip tray is too small to quickly flip 100 primers. 50 work great.
2. Primer tubes should be 4” longer to accommodate a counter weight.
3. Flipped primers.
4. Primer brand sensitive.
5. Works with CCI small pistol but small rifle, other brands and large primers flip upside down while filling.
Here’s my work around and this seems to be 100%.
1. 50 small pistol CCI primers
2. Counter weight now fits in tube.
3. Primers fill correctly without flipped primers.
4. Flip tray quickly flips all 50 as there is now room to agitate them into correct orientation.
Suggestions:
1. Make tray at least 2” bigger to hold 100 primers and allow room to job them into orientation.
2. Lengthen fill tubes 4” to allow for counter weight. Assists in primers filling press primer tube. Sometimes a primer gets stuck in the primer tube then when you take tube off press the remaining primers fall on the floor.
Bottom like with the work around the product fits my small pistol needs but is not a complete solution.
