I dislike that SO many men do not show a picture. The price is substantially more than most sites, and like everyone else, I fear that people are on this site strictly because they want someone with money. This site seems to be more responsible, posting adequate contact information. Some sites there seems to be NO way to contact them if you have a problem.
I agree with Tarkin1 - definitely more responses here than other sites like OKCupid, Match, etc. However we both know why that is - after all we are showcasing the fact that we are successful and women who want that type are here. So the pool is shallower and easier to find everyone in the shallow end.
Dislikes are the technology of the website. For example, I can email a non-paying member but she can only respond via message on the app (not on the website). Allows for many misses in communication (women don't realize this and miss certain messages). I think once a paying member writes someone - all communication via desktop/app should be open.
