I have found this brush to give the best results.
My order from Sleeve City came in today that included the Thunderon brush.
Took a pretty clean LP but not recently washed, just played last several weeks and carbon fiber brushed if I recall correctly.
I had every light on in the house so I could really see what was happening.
There was to my eyes very little dust on the LP. Something the Hunt brush could easily handle. However, the Thunderon was coming up with a lot of stuff I had not seen, I really didn't know where it was coming from, including hairs from nowhere.
And as noted by a user comment at the SC website indeed some debris was finding it's way over to the other side of the LP.
Jumping from one side to the other or just jumping off the surface like it was on the surfaced being brushed I could not really tell. However, some of it was crawling over the edge - tiny amounts.
I suspect my old West German wool army sweater was the source of some of the hairs. Maybe I have to hold the record even further from my body.
In any case, I did both sides 2-3 times until I was happy that all had been removed.
Listening to the LP now, The Cure, Kiss Me - Kiss Me.
Clean.
Real clean.
Static free.
Not a miracle, just science.
I estimate at least twice as much debris was removed over any other brush I have used, and I am being very conservative in my estimate.
The LP sounds better than most wet cleanings I used to do with my old fluid.
EDIT:
Just did sides 3 &4 of the double LP set. Took less time because I was careful to not let my sweater sleeve ends at my wrist touch the LP. That is where the hairs were coming from.
As far as dust removal, I will stick with the 2X estimate.
The aggressive large sweeping motions shown in the video works better than a slow meticulous circular path I used the first time and had to use with the Hunt brush.
Sweep away, and dare to be bold about it.
Just roll up your sleeves first. And if you have a big belly, suck it in, it's for a good cause. You want the system grounded via your fingers, not other body parts with hair laden clothing that can transfer.
