I've used them. First off, in Halifax the pickings are pretty slim, so overall they are not bad, but things can be improved.
First, there was a booking incident - them getting me confused with another client, changing booking people at the last minute, me not giving them enough information, the girl already on her way to another client, confusion over email versus phone, etc... etc... etc... In all fairness, when they were able to figure out what went wrong, they did fix it.
I had a duo with them. Overall, not bad but not great either. Not too interactive with each other, but on the other hand, not like mixing oil and water either. In fairness, they did say that as a result of the booking mixup they sent one girl to another location, and that girl would have been much better in the duo situation. CBJ/BBBJ, LFK and MSOG available.
Both girls were attractive, young and sociable. However, they are more Girl Next Door attractive, as opposed to being model-types. Personally I had no problem with this... it is actually what I prefer. I can say that things got a little boring and tired in terms of conversation, but on the other hand I don't know if I can blame them. With the booking mix-up by the time they got to my hotel room it was like 10:30pm on a Sunday night - everyone was a bit tired.
My one complaint is the price - $300/hr was expensive for the service received. If there were no glitches and if the experience overall were just a bit better I would have no problem with the fee. I'm typically not one to complain about fees, but I really just did not feel it was worth the money given all the minor issues. However, as I mentioned, I think many of the issues I encountered were unique, and in a market where there is not a lot of choice, they are not bad. I did leave with the impression that they are attractive girls willing to please.
