After viewing liveoak's thread on this tumbler, I thought I would give it a go. I liked the idea of the auto-reversing feature, though not sure if it's just gimic, or actually helpful.
So I want to coat the inside of the drum with truck bed liner. It's not going to stick very well to the high gloss finish that it comes with, so I decided to run 4 pounds of mostly unused small ceramic media DRY in the tumbler to basically sand-blast the insides of the drum. It worked quite well, the inside now has what looks exactly like a sandblasted matte finish.
I've seen several comments on youtube and other places about it being too fast, so I broke out my Olympus, setup my tripod, and did some slo-motion capture. Video capture was at 120 frames per second, which means I'm able to get very accurate RPM readings after a bit of math!
The speeds on this thing are kind of weird.... 1 & 2 are very close to each other 3 IS in-between 2 & 4, and 4 & 5 are also very close to each other, so close that I re-shot speed 5.... and oddly enough, with wash water in the mix (heavier drum) it actually spun faster.
I also found something odd.... when running in auto reverse mode, reverse runs about 15% faster than forward.... I'll be contacting Vevor tech support about that to see if it's normal or not.

One thing I was disappointed in... the round door instead of a hexagonal door as shown on the Amazon product page. I contacted Vevor tech support about it, and only the 6.6lb/3Kg version comes with the hex door.
This basically leaves space for small particles of grit to get stuck in and not easily come out. But this will basically be a stage 1 tumbler only anyway.
It's also a lot smaller than I thought it would be. It's 5% larger diameter as my 3lb Nat Geo drum, and barely over twice as wide, plus 4lbs of small ceramic media filled it half way.

Here's my Nat Geo 3-speed tumbler for comparison:
EDIT: Just as a data point, the Nat Geo full drum as shot in the video weighs 3lb 13.35oz
