I think it depends on which airport is your main airport.
Just about every time I use mine, I wonder why everyone doesn't. Lines are usually much shorter and faster, do t have to take off shoes, laptops out, etc.
Also check to see if any of your credit cards give you a credit to get it. Mine did, which is icing on the cupcake.
