My package only came with the user manual and not the actual duct slider tool when in the description it clearly says it comes with it. I didn't pay $59 for just a user manual. Like how does a mistake like that happen.Update:So I received the replacement for this shipment and once again it only came with the user manual. Not the actual duct slider tool. I ordered the actual tool and manual from the ACCA website. Much better off doing that for an additional $10 but it comes with everything including other resources. Pic above is what came from ACCA not Amazon. Don't waste your time or money.
