I just ordered one of these a few days back, https://www.aliexpress.com/item/Meg...-Magnifier-Electronic-Stereo/32827664508.html
$18 from China postage included ... I'll let you know if it's any good in about 4 weeks when it gets here....
I found some very reefy gold a while back that has cleaned up very nicely and I'm keen to get some up close photos of it, I figured $18 bucks was not too much. I loved the photos Minelab Gold used to put up of his gold under the USB microscope, but couldn't justify shelling out $150 for a name brand USB microscope...

Ok my USB Microscope arrived today, I took some experimental photos of my reefy gold.
I've had the gold soaking in Alibrite for about a fortnight, also I cleaned it lightly with a toothbrush. The gold is very brittle and some little bits flaked off when I cleaned it with the toothbrush, but I've saved every speck.
It's hard to get the focus just right with the flimsy stand included, but I guess you get what you pay for. Not bad for 18 bucks.
On close inspection I found that bristles from the toothbrush I used to clean the gold have gotten lodged inside the specimen. How am I going to get those out? Is there an acid that will dissolve plastic toothbrush bristles?
I also found this little hitchhiker on my stomach so took a little video of him.
Conclusions:
1. Reefy gold is cool.
2. We live in a world where you can buy an $18 USB microscope from China
3. Don't use a toothbrush to clean your reefy gold.
4. Ticks are gross.

When I was looking at the images that Dron put up I was thinking that is a cool device. Then I remembered that I purchased one myself 3-4 years ago and had never really used it.
So I fished out a chunk of quartz with some fine gold in that I recovered from up near Georgetown a coupe of years ago and had a look at it using the beast. Good thing. it really showed the gold quite clearly, bad was that is also showed that when I had smashed the big chunk of quartz and carried just some back to the car, I had thrown away a piece that likely still had gold in it as that face has more gold showing than the other one where I broke it in half again.
This is part of the gold on the face where I through away the rock that it was fractured from.
Oh well I know where I through those chunks of quartz, so next time I am back in the north I may go and have a closer look at them.

A bit more on this story, I note that the info on mine says it is 220x.
I had soaked the quartz in Alibrite for a couple of weeks and that cleaned most of the ironstone off and made the quartz surface grainy, and a bit friable. Now having a closer look at the specie of mine (the quartz chunk is about 2", x 1.5" x 1.5" sort of) to show others what the viewer could do I notice that there is crystalline gold showing on all sides, so I must have chucked away more than I thought. The viewer with its bright LED lighting also allowed me to view down inside holes in the quartz and find more gold inside the quartz chunk.
Folks here said smash it up, but I am happy to leave it as a specie, but I must try and find those other bits of quartz next time I am up in the Georgetown area.

Mate does it have a focus ring, I am very interested in this unit?

Yes, mine has a large focus "knob" and a fine brightness knob that allows the LED brightness to be adjusted through a reasonable range. Mine looks almost the same as that of the pic that Dron put up, except mine says its 10 > 220x (Dron ad. says 50 > 500x) and mine is white. Focus range is ok, but it is hard to get sharp images on stuff that has reasonable depth as is seen in the shot into the hole in the quartz.
As I said in my first post here, mine is several years old, and I can't find it available on line at this time, but the one put up by Dron looks to be as good if not better than mine.

Just to give a picture of the max magnification of my device, the following photo shows 1mm as the main graduation and .1mm as the smaller of the graduations. Also mine is for a PC USB connection and the viewer came with this calibration slide and driver software for a PC.

One last comment, the fine gold in this specie of mine appears to be crystalline in structure, which is perhaps another reason to not smash it, as I understand that crystalline gold can attract a lot more than ore value to an interested buyer, not that I am looking for one.
I could perhaps give it another dip in some Alibrite, but won't do that at the moment, as if the structures aren't joined up, I would end up with many little crystalline grains.
