| I assume you're talking about "Kai's Power Tools". These come in 3 non-redundant versions (ie: each is not a update, but entirely new tools).
The plugins themselves are wonderful. General opinion about their interface is split. Personally I hate it.
From a photo restoration-retouching angle, very few of the tools have any use.
There's one that can render photo-realistic skys based on your time of day and weather settings, which I've used a couple of times to replace faded backgrounds.
There's another that does unsharp masking but based on restrictions. Sounds great, but I've yet to figure out how to use it.
For other types of work, web graphics, etc., these tools are stellar.
