Shimano 8-speed

"While PL does not require special tools for install, the especially tight tolerances of 10 Speed drive trains mandated that each PowerLock is good for a one-time application only."

Huh. I did not know this. I might have to rethink my chain cleaning methods. Or, look into other brands that do allow you to take them apart.

Wippermann chains, including their 10-speed versions, come with the "Conex" link that installs and removes without tools and is reusable.  I've had excellent service from their 10-speed chains on several bikes.

+1 and I use the connex master link on all of my chains, 9 & 10 spd, regardless of the manufacturer.

The 9-speed Connex (spelled it correctly that time) is a universal fit for other brands of 9-speed chains.  The 10-speed Connex link is a good fit on KMC and Shimano 10-speed chains as well as Wippermann's own chains of course.  However, it is a bit loose when used on Campy or SRAM 10-speed chains as their inner plates are very slightly narrower.   Using the 10-speed Connex link on Campy or SRAM chains won't cause its failure but it's not a good fit.

I confess my 10 speed experience is limited and I don't recall ever owning anything made by Campy. But I do understand the plate dimensions are different but not the rollers. YMMV.
My one issue that I have had is with how they can cause jumping on the 11 tooth if put together "upside down."

Correct, the "inner" plate width is what controls how a master link fits and not all chains are identical. 

Also correct that the Wippermann Connex link has to be installed in the correct orientation to run quietly.  The instruction sheet that comes with their chains is very explicit on how to do it properly and it's not at all difficult.

Geesh thanks for the confirmation. BTW are you are you a teacher or is this just the way you are?

I'm not sure what you are asking or why but, no, I'm not a teacher.  Maybe worse, I'm an engineer.
