I've had Snap-on tools every since I started in the trade at 16 as my dad gave me a tool chest full that was like new as he hardly used them.
The chest is older than I am (I'm 30) and is still absolutely spot on, doubt you could say that about many other makes!
As for the tools, I can't really knock them either.
I'm in the process of replacing a lot of my tools after a lot of them got lost (not by me! ) and it's skinning me alive!!
