Fitted some gold blades on my Hobbit today and thought I'd post some pics.
Overall they look amazing instead of the black space, especially with Hobbits fancy lighting. Easy enough to fit and secure with a bit of double sided tape. I only used a strip near the flipper buttons and the hinge bolt playfield did the rest.
In comparison to the gold metal mirror blades fitted on my LOTR, they are not as good, but it's very close and they are half the price. They show slightly more distortion as they are quite flexible. Also if you look from the sides the depth of reflection is not as clear as the metal blades, they are a touch cloudier. But with both of these things you cant tell from a players position. Last thing, being really fussy, there is a thin white line visible along the top of the blade, but in reality you dont notice it.
Last point, if you are thinking of fitting these make sure you use the protectors from Pinball Center.
Cheers to Xianek for offering them and the great service!
