Keen has a couple introductory offers. One is, three free minutes with their dollar per minute packages. They also offer ten minutes for $1.99. Their psychics range in cost from about $2.00 to over $35.00 a minute. On the low end it is a little lower than average. On the high end it is much higher than average.
It does appear to be a network of psychics with no vetting. When this is the case you must spend much more time vetting the psychics personally by reading customer reviews and ratings in hope of finding a psychic that you connect with. I believe that the psychics set their own prices. This could be problematic, especially when reading with higher price psychics. Just take your time and read the reviews and make an intelligent decision based on the information in front of you.
Keen will only return up to $25 for unsatisfactory readings. You must email them within three days to receive this credit. Additional information in the email must be provided. This is not a refund to your card, it is only in Keene time. You can only get time back for one unsatisfactory reading a month.
Keen has been in business since 1999, and have over 1,700 psychics, so variety will never be an issue with Keen. Their search filters are not as extensive as other services. There are a lot of psychics that have been there for a long time, which bodes well for them and the service.
