TOMLOV TM4K Max 4K Digital Microscope 2000x, 52MP Spin Arm Soldering Microscope for Adults, 10.1" HDMI Electronics Repair Microscope with Ring Light, Larger Base LCD Coin Microscope Full View, 64GB

I purchased this as an upgrade from a DM9. I loved Tomlov products so much that I bought a DM5 for my grandson. He took it to school and everybody loved it. On to the TM4K. It did not disappoint. It was easy to use out of the box with minimal setup. Some of the nicest features: - The flexible stand allows you to set your object in place and the have the flexibility to move the microscope around and not have to worry about centering the object - The extended post allows you to get close to the image (in my case coins) and then fine tune the view with the adjustable knob - The zoom-in is great to where I can see tiny imperfections in the coin, great for checking for errors. - There is an 8X digital zoom that allows you to zoom in even closer. This worked great by allowing me to basically put the lens right up to the coin and then zoom in closer - There are tons of options to adjust the image before taking the image (the default settings work great for me, but for others they have options) - This came with the 64gb memory card already installed - I was able to easily connect this to my monitor for an even better view of the coin. The HDMI cable is included in the box. - I didnt think I would use the included remote very much, but I discovered it works great when reviewing the image on the external monitor The built in Ring light is great, but it does require an external power supply (110v). This also takes videos, but I haven't tested that feature yet. I will update the review later with actual images from the microscope. Another big bonus is the customer service from Tomlov. They typically reply to emails within 24-48 hours.

The digital microscope with this type of arm is great! The resolution is great, and the adjustable intensity ring light is very helpful. You can balance the intensity of the ring light with the built in light to achieve a perfect view. The various image adjustments and quality monitor make it easy to see the subject and take quality video or still images. The rack and pinion adjustment had a little too much slack in the gearing (gear lash) and the arm could offer a little more resistance to movement. I tried tightening the middle arm screws, but this didn't help. The large steel base is heavy enough to make the unit very stable. I use it for inspection of knife blade edges during the sharpening process. This definitely makes a difference in the sharpening process. Thanks for a great product!

Highly recommended for SMD work. The picture is definitely 4k clear and without any lag time like cheaper scopes. The arm is high quality, without any unwanted movement. I left the set screws out that prevent the scope from rotating in the arm and managed to route the power cables in a way where the screen maintains a forward facing position during 90% movement of the arm. A nice feature is that the lens can be positioned almost 1 foot above the table which allows plenty of work room, perfect for working on taller items or using taller PCB clamps. My only gripe is that the halo light must be loosened to allow rotation of the lens for focusing. The good news is that the microscope holds focus extremely well once you set it for your working height. I haven’t really played around with any menus or special features yet because works great out of the box.

Works well,nice to use

Good for the price in general. Good image quality and features. The included light ring could or either be USB powered from the unit or provide 5V to the unit. As it is you need two outlets (one for a USB charger and one for the light ring).
