I've seen her, too, but I'm not sure I would say her service is bad. I've had bad recently with another young blonde, and Stephanie was leagues above that.
I'll start off with the negatives. No kissing at all for me and I typically don't have an issue getting dfk, so I wouldn't expect it. Unless you count kissing her lips while she lays there, but I don't.
For her age and body, you wouldn't expect them to sag like they do, but they do. Make of that what you will based on your tastes.
After getting into it the bbbj is quite enthusiastic, but at first it's quite light. Not quite as tight as you might expect for someone so tiny, not that it necessarily works like that, I know, but still.
However, she was very nice and acted like a gf with cuddling and such to get things going, rather than it being overly transactional. She's personable and I enjoyed my time with her, even if the sex wasn't the greatest.
I don't think she offers great value at her rate level, personally, and I would likely only repeat once more, if that, but I wouldn't say she's bad, just not great.
