Here's one such case from Michigan which cites the "quality" of their affidavits. From the last page:
"Perhaps if Plaintiffs' election challengers affiants had attended the October 29, 2020 walk-through of the TCF Center ballot counting location, questions and concernes could have been answered in advance of Election Day. Regrettably, they did not and, therefore, Plaintiffs' affiants did not have a full understanding of the TCF absent ballot tabulation process. No formal challenges were filed. However, sinister, fraudulent motives were ascribed ot the process and the City of Detroit. Plaintiffs' interpretation of events is incorrect and not credible."
