My testing method was slightly different than placing the record on the table and gliding the brush/device over the record. I held the record in my hand while using each device. The Milty Gun and the Kirmuss Brush completely eliminated the static as well as the Boundless Brush. But the Kirmuss was a bit better than the Boundless Brush. I must state that they are my newest brushes with very little use. After my initial results I blasted the 5 other devices with the Milty Gun. The performance of the brushes improved to the approximate degree of the Boundless Brush.
I think my older brushes retained some level of charge as a result of more use even though they are insulators.
++1) Milty Zerostat Gun, the best. Effected both sides of the record from a one side application.
1) Kirmuss KA-B Combination Brush
2) Boundless Brush
3) Pro-Ject Brush
4) Audio Quest Brush w/gold handle
5) Analog Relax Brush
6) Walker Talisman
7) Audio-Technica Sonic Boom Brush/Pad. The Sonic Boom added static charge to the record.
