That's a bit of a blanket statement. I've had very positive experiences and some mediocre ones with this micro. So, basically the same as any other group of SPs.
I'm with TL on this one. I've seen a few stellar ladies at this place in the past year... Madison, Brooke, Miekela, Brooke2, and A hot latina girl (can't remember her name). All of these ladies have had positive reviews. However, 4958 has been known to post a few fake pictures for certain girls. I have not seen (nor will see) any of the girls there with fakes ads.
To put a blanket statement on each girl there as being dreadful is wrong. Unless Isildur123 has seen ALL the girls there? Maybe you'd like to give us more details about your time with Tanya?
