I've got their 'Mesawinds', 'Angelic Harp', and 'Angelic Zither' libraries. The former two I use regularly, the latter was more a 'thingy' I bought alongside the other two and have only really used once. Nonetheless, all three are great, and haven't regretted buying them for a moment.
The Angelic Harp is my no.1 harp and I'd recommend it to everyone. Of all the virtual harps I have (8 or so) it's the only one that truly, genuinly sounds like a harp to me. The magic's in the retriggered notes working like an actual harp playing the same string multiple times rather than a (round robin) sample being triggered multiple times. And also it doesn't sound so damn 'plucky', which is a problem I have with many a harp VI.
It does have a lot of bottom end, though, which can build-up a lot, so I always EQ a rather significant chunk out of it - but that's the only little minus I could give it, honestly.
