Snap-on rachet fail (bought used in 1967) and it was replaced without question. I bought a rollaway full of sae Snap-on tools at that time (1967) and have added a lot since. Oother than a 1/2" breaker bar that let go when it was tested with a 6' cheater pipe, that rachet was the first thing that I have ever had a problem with.
We also have an assortment of tools from s-k and about every other manufacturer out there, hate to even think about the total investment over the past 40 years, but the bottom line, as with most other things is that you pretty much get what you pay for. The 50 year old snap-on sockets will still hold better [are less likely to slip and fudge up the head of a bolt) than a brand new craftsman or s-k.
Since embarking on the MB hobby two years ago I have spent about $1,500 on metric stuff, but I already had the basic sae from 1/4" drive to 3/4" drive and open end/box to 3", along with most of what anyone would need for fixing almost anything mechanical, from pullers to hones, tire changer to milling machine. A fairly complete farm shop where we have done it all.

Should be one h-ll of an auction when I am gone.

Cheers,
JIm
