Top notch kit. Well built. Will serve pro mechanics day in and day out. A lifetime addition to the toolbox of a home mechanic. The blow molded case withstands abuse and keeps everything in one place and organized.
In my experience there are two types of tool buyers: The guys (gals) who want a quality tool they can depend on, earn a living with, or who value their free time when working on their own 'toys'. And then there are the guys (definitely guys, not gals) who just can't (won't) shake the few extra pennies out of their vacuum sealed wallets, who have the frequent flyer punch card at that Cheap Tool Discount store. (You know which store I'm talkin about, and you know who you are...)
Life is too short for cheap tools. I don't know about you, but I don't have time to do any job twice, or have to run down to the Cheap Tool Store and buy another cheap a$$ tool cuz the first cheap a$$ tool broke.
The Lincoln 58000 Lube Adapter Kit falls into the quality tool category. Buy it. You won't regret it. I still haven't figured out how Amazon consistently does it, but when I bought mine, they had the best price going!
