Thank you for your feedback and I agree with your comments. I reviewed Malco, Wiss and Mid-West specs for each tool and found they spec a lighter gage steel than Lenox. Lenox specs 18 gage for each of the tools and Malco, Wiss and Mid-West spec 22 & 24 gage steel depending on the application.
In normal use in construction I do not believe they use these types of tools on 18 gage steel.
Can you check the performance of these tools on 22 gage material before sending your comments to great Star?
I agree with your comments for the features, clearances and fits.
