"Provides some very good options"
Does what it claims
Doesn't messes up with the system.
No bugs experienced (the existing bugs have also been removed according to what I read on ghacks.net)
UI is awesome and I find it to be something very different from the conventional software UIs
No forum or help file
No option to search the tweaks inside it (as it has large no. of tweaks)
No automatic maintenance or tuning feature, all settings are applied manually (good for those who want to finegrain Windows, but I would prefer some automated settings as well)
All in all, a very good & stable software and is very reliable.
I think it does it jobs very well. And, has a hidden tweak for creating the much needed Shutdown shortcut on Windows 8.
However, when I used it on my old PC at home having Windows XP, then I noticed some tweaks didn't worked. I mean it worked fine on Windows 8 (and so I assume on 7 also), but some tweaks didn't worked on Windows XP. Note for the author, to make it more compatible with XP.
