No personal experience, but they've been around for a while.

and yes, they have reviews.

I've seen a couple of the ladies the agency helps to promote:  Nicolette Rose and Andria Anda (see my reviews).  The agency has good marketing and is known to help independent providers.  Levip will e-mail you detailed updates of the ladies touring your town, including the providers profile, latest pictorials, etc...

The pictorials of the ladies I've seen are accurate and current.  Being that the ladies appear to dictate their own terms, the service has been outstanding (i.e. no agency 'pinging' a provider during a session, no rushed sessions, no clock games, etc...)  I recommend hobbyists and providers to check them out

have never pulled the trigger on any of her girls, but i have gone to a le vip meet n greet.

andrea, the lady who runs it, is very nice.  i almost had a date last month with one of her girls, but car accident and broken hand delayed that.  i fully intend to follow through with the date later in the year when feeling better.

they are legit, the ladies at the m&g were pleasant (tho imo over priced, compared to some ladies i have met at ter m&g's).

i would not hesitate to go out with one of the ladies that strike you fancy, tho if there are no reviews on her, then its usual buyer beware, al though i would not say that because of the agency, only because of the toftt realities.  untried quantities may not turn out well, but you never know.

gotta say le vip has some good looking women working through them...
