Expensive but a very useful tool
I bought both the LensAlign MkII and the long-ruler kit. I don't love that the long-ruler kit costs as much as the original kit; that does seem a little much. There are no instructions with either kit, other than for assembling the device, but the developer, Michael Tapes, has plenty of articles, checklists, and free videos online to explain the concepts and walk you through the calibration process. If you suspect one or more of your lenses might be front-focusing or rear-focusing, this is a very good way of diagnosing and correcting the problem.

Lens Align and Long ruler kit
Good product to verify and correct your front or back focus issues. I would not personally recommend the long ruler kit though I assume it works as advertised. I worked with the standard kit for my lens up to and including my 600 f4

Good tool
This kit is, to my knowledge, the only one that allow the micro focus adjustments of long telephoto lens. The regular "kits" ruler is too short to visualize the out of focus zones due to higher depth of field.
Would have liked a sturdier kit but does the job.
Somewhat pricey but unique niche.

Works well but expensive
Was able to get more consistent results using the LensAlign for MFA then other methods I've tried. Tested lenses with focal lengths from 16mm to 860mm so I needed the long ruler in addition to the standard ruler. I have two complaints. First, it's expensive for a few pieces of plastic, thought if my images are in fact sharper after using it it is worthwhile. Second, there seems to be a number of versions/revisions of the product and the online instructions I found were not for the version I received.
