I am not familiar with STAR, but my son is currently wearing a DOC band from Cranio Tech and I can honestly say our experience with them has been 100% POSITIVE! I would highly recommend going with Cranoi Tech. The office is very child-friendly and the staff is willing to answer all questions you may have...at ANY time. One of the staff, Mindy, actually lives here and McKinney and said she's willing to make "house calls" if you need anything after office hours. Oh- and they call the DOC band the baby's "crown." I thought that was cute.
As far as the adjustment, I think you will be pleasantly surprised at how easily the babies adjust. I swear my son acts like he doesn't even know it's there. Since day one, he has not been bothered by it. Not once. It does cause some sweating, though, so you'll want to dress cool for a while. If you have any other questions, feel free to email me or call me.
