Not a good one!!!  I felt I was basically pushed out to go home before I was ready to leave.  I was still groggy and unsteady.  I also truly believe I was over anesthetized. I have never had such a reaction to anesthesia before and I have had many procedures.  Another thing was that their BP machine was not working properly.  I told them but, they really didn't listen to me,  After the procedure, they again wouldn't listen when my pulse/ox was only 85 and warning alarm would not stop.  Finally they, themselves realized the machine wasn't functioning properly after they had me pretty much hyperventilating. More to this but too long to explain here.  I was very unhappy with my entire experience and would be leary to recommend WAMH.  Possibly they had an off day, but was not a pleasant experience.
