It is not a clone tool. It does not replicate what the clone tool is
capable of. You have to dick around with it to get it to use the area
you want it to use which makes it less effective. Useful for some
things, but not as effective, and certainly not easier to use.

It is not the equal of the PS clone tool, but it is there and when used
judiciously it works. Once you have used it and understand when it
works and when it doesn't, it is reasonably easy to work with. You just
have to understand when you should move to PS as an external editor.
For complex cloning, patching, and where the content aware features
have to come into their own, LR cannot compete. However, for most
editing it does just fine.

Yes, Duck, I tried it a few weeks ago. It's useful, but not the same
as the PS clone tool. They've added some cloning features to the
Healing Brush tool.

they did a helluva lot more than that, and much of the time it's more
useful than what's in photoshop because they also optimized for common
use cases. that's part of how it increases one's productivity.
