Ordered 29 June 2022;  received 13 July
Shipped in a proper objective jar, packaged in a bubble-lined envelope.
The objective appears to be in a single solid metal casting
and appears undamaged, but cannot focus in my AO 120 infinity microscope.
FWIW, also cannot focus in (finite) Optiphot; return requested.
Front optic is recessed about 1mm into the casting.

vendor offered $15 refund Jul 14
I tested further by holding it backward for far distant view (nearly infinite).
Good infinity objectives can focus a far image on ground glass
at nearly their working distance, but this cannot focus at any distance.
It nearly focuses when touching ground glass, so negative working distance?
Optical elements may be shifted inside, but I sense no looseness.

15 Jul video demonstrating its inability to focus in comparison with another objective:

Nikon Microscope Objective BD Plan 60x0.70 ELWD 210/0 M26 Thread

eBay item number:   304609136243
Condition:   Used
The edge of the front lens was cracked, but testing did not affect imaging.
received 23 Sep 2022

Damage appears no worse than in eBay images; it easily passes monitor subpixel viewing test.
In the Optiphot, it is neither fully parfocal and parcentric with the BD Plan 60/0.80,
and contrast is noticeably lower, but an acceptable trade-off for sustantially increased working distance.

  • WHY USE AN ACHROMATIC LENS? An achromatic objective lens corrects for color and has a flat field across the central portion of the microscope image. We use dual lens technology in our compound microscope objective lenses to meet this goal. This objective lens offers high quality observation without additional chromatic aberration, which leads to a clearer microscope image.
  • DESIGNED TO LAST: The microscope objective lens is built with tough, lab quality materials designed to stand up to everyday use. Each objective lens goes through a rigorous inspection before shipment to ensure you receive the highest quality item that you ordered.
  • HIGHLY COMPATIBLE: The microscope objective lens is engineered to fit microscopes with a 20mm thread
    such as AmScope, Canon, Nikon, Bristol, OMAX, Olympus, Swift, TELMU, and many others.
  • SPECIFICATIONS: 60X Standard NA/0.85, DIN 160/0.17 achromatic objective lens, Field of view: 0.29mm, Working distance: 0.5mm, Mount size: 20mm thread, 20.2mm standard RMS interface
  • AMERICAN COMPANY: Reticle Optics is an American microscope lens company.
    If you have any problems with or questions about the achromatic objective lens,
    our customer service knows this product well and is ready to assist you.

Compared with PL 60 /0.85 160/0, view of calibration slide without cover glass is much lower contrast.
