I like Tara, overall. Sometimes she can be a little testy but that only happened once so I give her the benefit of the doubt.
For timelines, she's been accurate for me, for the most part. The one time she gave me a timeline that didn't happen, at the outset she told me "I think this is going to happen around September or October, the fall timeframe, but this unfolding situation could push that out." So she warned me, and sure enough the situation did push the timeframe out. When I called her back, she said she could not predict a timing because of the nature of the situation and how much has to fall into place first. She gave me a timeframe of a couple of years out, but made it clear that was just a feeling, not direct from spirit.
Overall, her timeframes have been right for me. But she has also pushed them out - but that bothers me less, because she warned me from the outset that it could happen. I feel when she doesn't know she will say so and that is kind of rare among psychics.
