I don’t have experience with these lenses.
There was a thread not long ago about Vervor Microscopes that were fairly affordable. (less than these lenses). The Vervor looks just like my Otto Frei setters microscope.
Whatever you chose make sure that you verify the return policy. Magnification is a very personal decision. You probably won’t really know if it works for you until you actually use it for a week or so.
Sorry that I can’t be more help!
