Presumably you are referring to the highly promoted but largely unneeded "A Frame Wind Kits."
The inventor/owner was on this forum about a year ago selling these. His campaign was long on fear factor sales but short on engineering. Little things like explaining exactly what types of wind were dangerous to A Frame owners, how likely these conditions were to occur, and evidence his product actually did what it claimed.
His posts were filled with FUD tactics. (Raising Fear Unease and Doubt.) After reports to the forum moderators, at least one thread disappeared and his posts were heavily redacted before the thead reappeared.
According to his own word
, he is not allowed to discuss the product here. Although you and anyone else certainly should be free to.
See this tread for a prior discussion.
