Great quick-change for anything that goes on a mic stand...even parts of the stand itself (i.e. boom to stand base, goosenecks etc.).
Pros: very well made, safe, instant clip on action, easy release system, not too heavy.
Cons: none really tbh...maybe if you're already close to the max weight with a particular mic position, it will tip the scales...
TBH, if you have the money, it's probably worth dumping/selling off your existing stands and going all Triad rather than retrofitting.
The hex lock feature is a great idea; shame it wasn't also on the head part.
