I have these really high-quality screen protectors since nine months on an EOS 450D. Despite frequent use of the camera even in harsher environments, he still looks like new. So I also have the same missed him my new 50D. The noble glass is provided on the bottom edge with a narrow glue line, which sits the already black screen border only on the. It can be detached without residue with a hair dryer and then even use a second time (I've tested involuntarily after I only rotated by 180 °, the glass was placed). Highly Recommended!
