TOMLOV 1000X Coin Microscope with 4.3" Screen, Digital Microscope Magnifier with LED Fill Lights, Metal Stand, PC View, Photo/Video, SD Card Included, Windows Compatible, DM4S

I will preference my review with my qualifications. I have dual degrees in biology and chemistry. I'm also an amateur astronomer, maintaining many telescopes in an astronomy club. I've built telescopes and I own a lab grade, true 1000x microscope. I know a bit about optics.First, the claim of any of these digital microscopes of reaching 1000x is marketing nonsense. I own a microscope, and have used others in the lab at 1000x. The multi-lens, Plano objective, required to reach (and resolve an image) at 1000x requires oil immersion with a special oil. My advise to people is usually, when you see a microscope or telescope that advertises high magnification, don't buy.I needed a simple magnification system for jewelry, to see inclusions and hallmarks, without spending a lot. My microscope isn't the right type for this. I chose the Tomlov because of the gooseneck lamps and many good reviews.I'm blown away. First, the maximum usable magnification is possibly around 150-200x (I'll measure and do the math to add to the review). That's the magnification I need and most likely more than enough for 99.9% of people.I was very surprised at the quality of the images. There's no vignetting. The image was clear and flat across the entire screen. It was steady, well-lit. I appreciated being able to adjust the brightness of the objective led's and gooseneck led's separately. The base is metal and stabilizes the scope.The microscope is intuitive. I never looked at the instructions. I screwed the scope into the base, tightened down the retainer, plugged in the usb, and, put my old mine cut (OMC) diamond under it. The colors were true and I could see through it. The whole image was as clear as a bell. I can move the gooseneck lamps to illuminate different angles, which enables me to see jewelry hallmarks, which tell me assay information, like year made, metal purity, city of assay. These marks are tough to see in a loupe and even tougher to photograph. I photographed them easily on my windows computer.You simply plug the provided data micro USB cable, into the microscope head and computer, then use the camera app on the computer. If you plug the dual cable into a 5v USB recharger and then into the base, I'll power both sets of lights. If it doesn't work, switch to the other mini plug on the dual cable. To use without the computer just use the dual mini USB cable, plugged into the scope and base, then into a 5v USB outlet (or charge).The rack and pinion height adjustment is adequate, but needs frequent tightening. The focus adjustment works smoothly. The height and focus stay put after adjustment. The optics easily magnified the inclusions in a sapphire ring that were impossible to see with a 30x lighted loupe. I'll post photos tomorrow.The scope was less than $50. It has features that match many stereo microscopes costing $200. It's not perfect, but at this price I would have been happy if it it did half as much. It was a pleasant surprise and deserves a 5 stars.I've updated the review with several photos. The scope is hooked up to the computer. I've imaged my 1/2 carat OMC diamond. I took photos at the least magnification, mid magnification, and the highest I could use with good magnification. That circle you see on the highest magnification is through the stone, showing the bottom point (called a cutlet). Over 100 years ago they flattened those points. This diamond has a small cutlet that I'm sure is around 1/4mm. The ring is 18k gold.The second set of photos are of a sapphire and diamond ring. I went from least magnified to as much as I could to photograph inclusions in one very small area of the sapphire. All real, natural sapphires (ie. mined and not lab grown) will have inclusions. The photo shows these inclusions, which are too small to really resolve, but for my purposes, is more than enough. It shows that this sapphire is indeed a natural sapphire. The hallmarks are English. They tell me that this ring is 18k gold, that it was assayed in Birmingham, England in 1992.If you want a scope to do more than this, than you'll have to invest in a true geological stereo microscope. A good one will cost anywhere from $500-4000.

I love this thing. So much I bought another to send to my coin dealer. It is clear and fun to play with. You can adjust the height and focus very easily. Heavy enough that it won’t move all over the table while adjusting. Good value for the buck. Takes the time out of using the loop for every coin. But one you will not be upset. The only thing that is not battery powered is the secondary lights they need to be plugged into a USB port. But I rarely use them as the light on the camera is bright.

If your going to mess with small things, get one of these. Cheap, saves your eyes and remember, you get what you pay for. Dates on coins, electrical wiring, threading that needle, etc. Has it's flaws but for the price it's really handy.

For an inexpensive set, It was clear enough to fix seriously bent pins on an Intel processor that would not boot prior. So I'm happy, I didnt think it would work, but it did. A more expensive set would maybe be better for those who do these repairs often, but it does the job so I'm giving it 5 stars.

Works great. I no longer have to strain my eyes to see a coin up close. Also was a great price, as well. Thanks

Fantastic scope image quality, fantastic, super simple to use.

For the cost, I think overall it’s a good purchase. There are pros and cons to this digital microscope though.The pros: you can use it on more than coins. It can be used on stamps as well and so many other things. It has a very clear image and the ability to photograph or video is an added benefit. Easy to set up and operate. Easy to charge, uses a cell phone type C charger.The cons: you cannot view an entire coin, not even a dime. You have to move a coin around to view it in its entirety. I think the surface of the base should be something other than metal, as it could scratch a coin. The base lights charge separately from the screen of the unit. Would be better to have one charging port.
