For me she has been on and off. During my very first reading she nailed everything or almost everything. She even gave me a warning, saying I should pack all I really need for my upcoming trip in my carry-on because something will be misplaced and it won't be the end of the world but it will be inconvenience for me. Well, it was - the tag on my check-in bag had fallen and it ended up elsewhere and it took 2 days to get my luggage delivered to me. That was jaw-dropping. She also predicted my job 2 years before it happened. She gave me specific details. But she said that would be the spring of the year when I called. It was in spring exactly, but 2 years later. I had a few more readings with her and when I asked about this guy I was really interested in, she started with him, then suddenly called him George, confused me with another caller, then said she knew he recently had a baby with his wife but he liked me. I was even more confused. There was a colleague at work who kept flirting with me and just had had a baby with his wife and I did not care about him, but she described him and that was him. I started giving a physical description of my POI to make sure she only concentrates on him, and she kind of zoomed back on him, but then jumped back to that George again, and I knew no George. A few months later I could figure who George was but he started work at my office 2 weeks after that reading. And since apparently the reading was a composit of 3 guys, it was hard for me to decide if any of this would happen. I still don't know.
When I was breaking up with an ex, she repeated something she told me about him the first time I read with her about him. Back then, he said, "he wants a life with you; he wants to build you a house; if you say I want a puppy, he will give you a puppy, anything." It was almost scary, when that guy said those almost exact same things to me. So, during the breakup reading, she said, "He loves you, he really wanted to build you a house and give you everything you want." Well, at that point I knew what he was and I knew what he wasn't. He did want to build me a house and all that, all right - only in the realm of words, though, because he could do no more but big words. He was just the type that says all these things even if you don't ask for them. I guess he likes how they sound, but he could not ground himself in the real world or deliver on anything except some super small things.
Lastly, I had 1 reading with her as a medium and she nailed a bunch of things.
I would say, she certainly is gifted, but timelines could be so far out that people may think she didn't get it right. Especially since she has given time prediction with confidence. Also, I don't believe she ever gives a cold reading. The only problem is that when she mixes energies, you can be watching to see this manifest with your POI, and you may think she got it wrong because it is not happening.
I don't know what it takes to have a reading without having all kinds of people I don't care about involved just because I work near them or simply know them. Maybe quarantine isolation helps...
