As for first impressions: fit perfectly. Nice and snug. Was worried it wouldn’t come off easily but managed to pop it off without an issue. Color seems to be identical to the play field. Blends in well.
Sits right against the playfield. I was worried that there may be raised edges but it it perfectly against the playfueld. Seems to have no issues with a lip that might roll or block the ball (like a cliffy).
Even my girlfriend who isn’t into pinball as much as I am said she really liked it and commented if there was a lime green protector for our Attack From Mars, she would want me to take the cliffys out to install it.
Which speaking of, installation was a breeze. It took longer to remove the glass then it did to get it placed correctly. It took me 4 hours to install the full cliffy set for my attack from mars. I had to remove playfield parts and motors. Something like this could have a full install in under 10 minutes.
I’ll update this as I continue to play the machine. Only issues I see maybe occurring is a 1/1000 chance the ball rolls back or after thousands of hits, it starts to thin/wear down. (Although how about those MBr protectors bending after 200 plays)
