JJC Slide and Film Digitizing Adapter Kit

I have a few different ways to digitize 35mm film: dedicated film scanner, flatbed scanner, cheap CMOS digitizer, and old school film/slide holder for use with a digital camera and macro lens. I use them all depending on the purpose of the moment.
I became curious enough about this JJC product (which is a knock-off of the Nikon ES-2 kit) to buy one:

It comes with more lens adapter rings than the ES-2, and also more options for extension. That makes it possible to use it with my full frame camera and either my 50mm macro or 100mm macro, or with my APS-C camera and 50mm macro.
One slight annoyance with my personal gear is that I can't make the extension short enough to entirely fill the frame using my full frame camera with the 50mm macro. At the shortest extension, the lens can provide only about 0.9x magnification instead of 1x, meaning the final pixel resolution of the image is slightly less than optimal. That's a result of the design of the lens housing, so it will likely be different with different lenses. Not a big deal, really.
The extensions and lens ring adapters are all metal. The film housing is plastic, as are the film and slide carriers. The plastic seems okay for the purpose, and the carriers are easy enough to work with.
There are a few things that could stand improvement:
The tolerance of the sliding carriers in the film housing is not ideal. There's room for some slight tilting. I fixed this by adding bits of thin, dense foam to the slot in the film holder where the carriers sit. That eliminates any play and keeps the carriers level.
The detents for side-to-side frame placement also have slight play of over a millimeter rather than reliably locking in a fixed position, requiring visual adjustment every time.
The light diffuser is good, but too close to the film plane IMO. It's close enough that dust on the diffuser might be inadvertently brought into focus, so it could need frequent cleaning. This appears to be the case with the ES-2 as well.
The impression is favorable enough overall, and I'll probably keep the kit because it offers some advantages over the film-era Accura duplicator that I've had for years:

There's no point in including digitized captures because the actual results depend on the camera and lens.
