More about the product

For microscopes the resoluting magnification can be calculated by multiplying the focal lenghts of the objective lens and the eyepiece. Thus, a 4x objective lens and a 10x eyepiece gives 40x magnification. With the same objective lenses, but 20x eyepiece the magnification rises to 80x.
All of the eyepieces listed are for the standard 23.2mm focusers (except for the 30mm Zeiss standard), which is compatible with most of the biological microscopes.

The 10x eyepiece with measuring reticle can be used to calibrate the microscope and perform measurements.

Pros

Rubber seems to be of decent quality. It does the job when carefully adjusted.

Cons

The part that should be encasing an ocular is too wide. An inner rubber baffle does it instead, and that's not how it's supposed to be. Outer perimeter is supposed to grab the ocular and baffle should limit the movement and sit on top.

Summary

Too expensive, but difficult to find online for some reason. This is the best one I could find even though it's too wide.
