The only problem I've had with KMC missing links is dropping one half into gravel or long grass.(@!!*!) Reused them more often than is wise and have never (yet) had one fail. I always carry a spare, which came in handy to replace a bent chain link recently.
To save buying a special removal tool, I filed a notch in both blades of a pair of cheap scissors with a round diamond warding file. A bit of strong woven cord threaded round both pins can also be used to open the link.
I've never had an issue with reusing those links. I have, however, once had a shimano chain break on me when I was pushing hard up a hill. It broke at the weird rivet pin thing that shimano use. Probably my fault in how I fit it in the first place, but that only tells me that the fitting wasn't as idiot proof as the kmc one.
It failed exactly where you'd expect. And yes, I carry a spare!

KMC 11 speed quick link, tested to destruction. This one lasted 2 years of all-weather commuting, probably going through 25-ish reconnection cycles.

The KMC single speed missing link is also meant to be single use. But with the ease of cleaning the cogs, I have never wanted to remove the chain. It's only when deep cleaning the 3x9 drivetrains that I ever felt the need to undo the quick links, so I can remove and really get into the jockeys and cogs.
So I now carry around 8, 9 and single quick links. And the Park chain pup, and my original Cool Tool. Oddly in the past 20 years I have only ever had a chain fail once, a 9, at the quick link.
But my first mechanical when I got my new mountain bike in 92 was a dead chain, and I had nothing.
Several others have been impressed when I have given help using a workshop tool though.
If the missing link is not reusable - and you need a chain tool in any case to get the correct length - what is the value of the missing link?
I carry spares so I can repair the chain if necessary (never needed to with KMC chains). If the chain snaps at another link, you've got the option of removing the broken link (with a chain tool) and then joining the ends with a missing link.
I've also re-used missing links several times without issue.
It's far easier to fit a missing link than a loose pin correctly IME (though a competent mechanic may say otherwise). I've reused 9 and 10 speed links that aren't too worn, though wouldn't do push my luck.
I've been running 11 speed since February and have re-used my link about 4 times to no ill effect so far. You can buy 4 SRAM links on Amazon for about £12.
The 11x missing links are £12.50 for 2 so only £6.25 each...
Apparently so. Although I am sure I've taken one apart before.....
For the same gold effect, simply don't lube your chain for months. Result= nice golden patina, orangy gold and squeeky.
Is the missing link different to the one on their 10 and 9 spd chains then? I've been using them repeatedly for years with no issues what so ever.
