I have a sneaky feeling those Visible Dust brushes are nothing more than white nylon (acrylic paint brushes) soft flat and fan brushes. By blowing air over nylon hairs it creates a static charge to pick up dust. And only less than 5.00 a brush for high quality brushes, too. I'm going to test it out.
I don't recommend. I have their Outdoors Photographer's Optics First Aid Kit.
Their "Tiger" cloth is no more than a standard spectacles-cleaning cloth, and does not absorb oil well at all. It ended up smearing more oil onto the glass than removing them.
The speckgrabber might be good for getting large, visible specks of dust off the sensor or glass, but if you're going to dabbing the sensor for all the sub-visible dust-spots, you might be better off using the Copperhill method or the SensorBrush. I dabbed my sensor a little too hard, and it did leave a bluish residue/mark which could be clearly seen by the eye.
The antistatic brush is usable but is not meant for use on the sensor.
The cleaning fluid looks ok. I have the Eclipse fluid too, and both perform similarly.
I have a speckgrabber and have used it a few times. It can leave more marks than you started with if you dont clean it super well. The only thing is you kind of need to map out where the dust is to grab it and that is kind of annoying. But I would pay the 3 bux to buy one if I had to again.

Summary: Highly likely that Visible Dust Products nothing more than nylon brushes...
Very interesting read. Time to shop for artist brushes.
