Not sure about recent, but I enjoyed Karma earlier this summer. I would have no concerns about her providing good service. She gets 5 stars in my books, great service and damn fine looking and sexy to boot.
Karma has been around for a while and I don't think you really have to worry about a "best before" date with her. If you can get into see her, you are good to go my friend.
Tomorrow (Saturday) is her last day at Legends until she returns again. She's working a double. Make an appointment because my guess is that she'll be booked VERY solid.
