I saw Nika in Melbourne. She was in great shape (obviously, as she was here for the comp). She was very kind, not a clock watcher, and happy to have her muscles appreciated. She was perhaps a little tired with jetlag, and she didn't offer any extras. Perhaps debatable whether or not she was worth $400/hr. I suspect she would have had me stay longer, but I had to go after about and hour and a quarter.
If you are expecting something like the Jana Linke-Sippl experience, you'll be disappointed, but it's still amazing to experience a body like Nika's.
