Choosing a digital microscope for soldering, PCB inspection, or coin work usually comes down to a trade-off between magnification flexibility and workflow convenience. The TOMLOV TriL110 and the TOMLOV 4K Autofocus Spin Flex Arm model both put a 10-inch-class screen on your bench, but they approach the job differently: one is a three-lens 2K station at a lower listed price, the other is a 4K autofocus scope with a repositionable arm. Here is how to pick between them.
Quick verdict
If keeping the purchase price low while having access to a wide magnification range matters most, the TriL110 is the straightforward choice. If you want 4K output, autofocus assistance, and the ability to swing the microscope around your workpiece, the 4K Autofocus Spin Flex Arm model earns its higher listed price.

Where each model wins
TOMLOV TriL110: The listed price is the lower of the two, and the triple-lens rotating barrel gives you two distinct magnification bands - a coin lens from 2X to 1000X and a biological lens from 2000X to 2500X - without swapping optics. It also includes 14 LED lights, a wireless remote, and 64GB of storage.
TOMLOV 4K Autofocus Spin Flex Arm: It steps up to 4K output and 52MP stills, uses TOF and AI autofocus to reduce manual adjustment, and mounts on a 360° Spin Flex Arm so you can position the head over the work. A ring light and remote control are part of the package.
Product notes
TOMLOV TriL110 10" Digital Microscope 2500X Soldering Microscope 3 Lens 2K HDMI
The TriL110 uses a rotating barrel with three lenses, which is a quick way to move between low-power coin inspection and high-power biological viewing. The coin lens covers 2X to 1000X, while the biological lens reaches 2000X to 2500X, so a single head handles both wide-area scanning and fine detail. Output is 2K HDMI video and 24MP stills on a 10-inch display, with 14 LED lights for illumination, a wireless remote, and 64GB of storage. The trade-off is that this model captures in 2K rather than 4K, so if ultra-high-definition video is essential, you will need to look at the higher-priced option. At USD 136.99, it is the lower-priced way to put a three-lens 2K digital microscope on your bench.
TOMLOV 4K Autofocus Digital Microscope 10.1" Spin Flex Arm Soldering Microscope
This model is built for soldering and electronics repair where the scope needs to move with you. The 360° Spin Flex Arm lets you swing the 10.1-inch display and camera head around the work area, and the TOF and AI autofocus is designed to reduce continuous refocusing during longer sessions. It delivers 4K output and 52MP stills at 2000X magnification, and the package includes a ring light and remote control. The listed price is USD 259.00, which is noticeably above the TriL110, and the maximum magnification listed here is 2000X, below the 2500X biological lens on the other model. If your work is mostly small PCB joints and you want autofocus plus arm flexibility, this is the one to consider.
Final choice by use case
Choose the TOMLOV TriL110 if you want one microscope that can scan a full coin at low power and then jump to high biological magnification, and you'd rather keep the purchase on the lower end of the price range.
Choose the TOMLOV 4K Autofocus Spin Flex Arm if your daily work is soldering, SMD inspection, or any task where you want 4K detail, autofocus assistance, and a scope that can swing around the bench, and you are comfortable with the higher listed price.
For a workshop where the purchase price matters most, the TriL110 offers more magnification range for less money. For a workspace where the camera needs to reposition quickly and autofocus saves time, the 4K Autofocus model is the more capable workstation.
