Our previous product (Virtuagirl2) had a very good retention, you can check the real time stats for that here:

The new HD version we just released enables surfers to buy girls individualy rather than subscribing. This enables surfers from more countries to buy, gives a chance to more people to try and see the quality of the product and brings money upfront rather than after months. Actually, most customers buy more than once. The average guy tries to buy one girl for $2, then comes back a few days after and buys a bigger package and so on.
Here are stats of an affiliate sending us traffic from a free site dedicated to our desktop strippers. Most affiliates saw their income multiplied by 3 to 5 with this new version, hit me up if you need anything to promote it.
