I was quickly given the opportunity to use these cards in my professional practice. I didn't tell the client that I was using cards but instead just followed the flow of the conversation. The cards fit right in. And were very accurate. When I purchased these cards I was worried I would regret it. I have not regretted it and think that you might want to give them a try also. I have used them twice in the short time that I have had them and they are very useful.
