Broken Defective Hart 20v tool to Dewalt 20v battery adapter

Description

new Hart tool to DeWalt battery adapter. Condition is New. Color is black.
These are not broken but i must be more and more dramatic in this listing to prevent foolish purchases of these adapters.
Even with dramatic warnings some people still buy these adapters without comprehending the adapters limits.
So it is now listed and sold "as is" and "for parts" without refunds.
make sure to study the compatibility limits of this adapter before purchase.
many people use these adapter regularly on SELECT tools
any questions i am happy to answer
for sale :  1 battery adapter to make modern DeWalt batteries fit on a FEW new Hart tools.
