Has onybody had any experience with Advent (@dvent) IT training company?

I'm looking at retraining and changing career and I have spoken with this company about the posibility of training in IT skills. They seem very genuine and the courses and career opportinities look very good (though I will check the careers and salaries myself). Has anybody trained with them and gone on to a good career through them? If so I'd like your comments, good or bad, please.
