So, ask yourself the question: How lucky do I feel?
Some of us are gamblers, and some are super cautious.
Do you trust your gut feel, aka Spidey senses?
As long as you feel OK with taking the chance and living with any result you get, then so be it, go for it.
If you are a "buyers remorse". kind of guy, then stick to the well reviewed.
What you may find is that she has seen many guys, but has asked each to NOT write a review. Many gals are very self-conscious about reviews to the point that they can't stand the pressure they bring. To that end, don't let her know about your TER identity. This way you can write a review without her being aware of it. Be sure to let the full 3 months pass and change a number of inconsequential details to throw her off the scent.
For the two or so gals I saw without any reviews, I had emailed back and forth with them for a while such that I had a pretty good feel for the person I was going to see. Both cases turned out very good.
Hope this helps.
