Yes I would like to find our the difference between the one for 350 and 500?

Here are the main differences between the two best options: The USB Digital Microscope for R350 (40-1000x magnification) allows you to view very fine details up close. It offers a wide zoom range so you can clearly see both small and large samples. The 500X Portable Digital Microscope for R345 provides 500x magnification, which is sufficient for most use cases. It's compact and portable for observing items on the go. Though its zoom is fixed, the lower price may be preferable if your viewing needs are not as demanding. Both are quality microscopes but the R350 model with its flexible zoom may better suit your needs if extremely fine resolution is important for your work. Let me know if you have any other questions!
