Quoted from michiganpinball:My Tron Pro (which is on location at Marvin's Mechanical Museum in Farmington Hills Mi) has the Mantis and shows little to no wear. I can take a picture later this week. It has thousands of plays also.
Thanks for this info. The first thing I did when I got my Tron in the house was install rails under the playfield then the Mantis protector then I powered it up.
