TA-102 fo.Q Product from Japan "TRY These"

Correction - I have compared it with AVM. - fo.Q works much better and produces subjectively similar results, but AVM had the benefit of being non-conductive and therefore excellent for use on circuit boards. fo.Q has the benefit of being removable.

Has anyone used the TA-102 fo.Q on glass windows? I was wondering if these could substitute for the pricier Marigo Dots.

I have never tried that. I'll try it now and get back in an hour. 

It only took 5 minutes to do the window test. It didn’t work very well, no noticeable improvement, a waste of good fo.Q tape at least in my listening room. After the test, I took the strips off the window and stuck them to the underside of my PrimaLuna amps where I have not used any fo.Q before. A huge improvement immediately on the amps. (I hope the glue doesn’t melt, but even if it does it won’t do any harm under the PrimaLunas).

edit - under the PrimaLunas is really a knock-out!

For Windows can I suggest my Flying Saucers for Windows? Small 1” copper foils. They’re even directional. One per window. Crystals are effective on Windows, too.
