Kudos to your engineers!

Ingenious mechanical design! You might consider future product labeling to lead homeowners directly to your home page featuring how-to videos.

I first encountered two "fallen" balances left disconnected by the previous homeowner and I could not for the life of me figure out how the hell they worked.

One window had never worked for us in our new (lightly used) 20yo FL home and my wife made it clear that the window was becoming a real "pain in the ass. (BTW,that's the way she motivates me).

Lizards and ants were using this window as a portal. It had to be propped up when opened and of course, the ugly props cluttered the sash when it was closed.

Your videos might have actually saved my life today. I respect a company that offers help like that
