Tolanalyst...any opinions

My company is considering buying a seat of Solidworks premium for the simulation tools.  One tool that I was mainly interested in was Tolanalyst.  I've seen a presentation on how it works but I'm still not 100% sure it will be extremely useful.  We have assemblies with ball type joints, and angular contacts.  It looks like Tolanalyst only analyzes tolerances of dimensions that are parrallel.  Anyone use this tool often?  Any reviews?SolidworksGeneral
