I was impressed by the packaging of the glass counter, multiple wraps of cardboard and foam.
As for the install there was no instructions but a quick youtube search on the counter revealed its essentially 4 screws and slide of the old glass off... I would say it does help having another hand, our glass was cracked already so we wanted to be carful when removing. Also sliding on the new glass and seeding it really does need someone else to on the other side to help guide it. Overall... don't spend the money for a repair tech when you can do it yourself in about 30 minutes.
