They work. 1. Use real pics. 2. Know your pay grade or league, in terms of physical attributes. 3. Chat for a week before you expect to meet. Stay in your age range. If you are realistic, get to know the other person, tell them what you want, listen to them, you have a shot. It takes a bit of sifting, but that is part of it. Looked for 6 months. Found my match and I am still with her.
