No, I'm not a fan of Greenfield products, as I believe them to be very poorly designed and engineered, but my customer has paid through the nose for one, so it's my responsibility to fix it
Hello Tentimes
You did say later, "I understand where you are heading and while I had a bit of a
rant to start with, I don't think it would be fair to focus on the company itself."

I feel you need to address this directly with Greenfield Products.
It may be they have an in-service fix, if the problem is as you describe.

This takes nothing away from your expert observations, nor your asking here
whether folks have had a similar experience. Thanks also to Norm for identifying
associated issues with non-dealers seeking help.

Perhaps an image or two might explain your concerns to a broader audience.

Hope this helps.
