I have been using the screen protectors from Expert Shield for years. The fit/coverage of the screens fit the screen on the cameras perfectly. Once on the camera, I have not needed to replace them (YMMV depending on your use/abuse case). The screen still remains perfect after years of removing/putting into bag, minor bumps, scratches against keys & objects, pokes with pens & stylus. Touch functions remain the same compared to without protector. Here are a few notes from my experience with them.GLASS - thickest of their products. Best for those cameras with a tilt-screen (ie EM10 series, EPL series). You can put these on an articulating screen however you will NOT be able to close the screen when it is facing the camera body. The thickness will not allow the screen to catch on to the latch to keep it closed. Very durable. Had it on my EM10.2 for years and still looks as new as the day I installed it.Crystal Clear & Anti-glare - thinner than GLASS and is best for the models with articulating screen (ie EM5 series, EM1 series, PEN-F, EM1X). Allows the screen to close facing body with zero issues. Protects against scratches and minor dings, maybe not as well as GLASS but I have not had a problem. I usually keep it closed anyway if I'm moving around a lot or jostling in a bag.GLASS & Crystal Clear - great if you shoot indoors a lot, not as great if you are outdoors on a sunny day. Does not affect the brightness or colors of the screen. Requires more wiping especially if you have dirty, oily or sweaty fingers. I have noticed the screen gets a little 'tacky' at times when it is not clean. It can be a nuisance if you are looking through the EVF & using the thumb tracking pad to move the AF point. Between the oils from my nose touching the screen or sweat from my thumb, it will sometimes make moving the AF point take longer than if it was clean.Anti-glare - my new favorite screen. Solves the issue I had above as the matte surface allows my thumb to glide smoothly even if its oily or dirty. Definitely the better option if you are looking at the screen on a sunny day. May make the screen appear to be SLIGHTLY less bright, but I have not had any problems using it at night or dark conditions. Does not really affect screen appearance or colors, though you may notice a slight haziness/dullness when looking at an extreme angle (which would defeat purpose of having an articulated screen). This is something that affects all products that have anything 'anti-glare.' In real-world use, I have not had any issues at all.Customer service - TOP NOTCH. They replaced the protectors I ordered recently for EM5.3 (1 defective, 1 user install error) for free. Emailed them about problem, took my order number and got a replacement set of 2 in a few days.A few installation notes:- Watch the tutorials on their website or on Youtube- Install in a dust-free area or steamy bathroom (the steam will minimize the amount of the dust in the air)- After you have the screen protector positioned how you want it, tape the protector to the screen on one side using some painter's tape. This will keep your alignment and allow you to practice 'dropping' the protector before removing the protective film- Use a credit card edge covered with a microfiber cloth to remove large bubbles without damaging screen. I sometimes got microbubbles but those usually went away after a few hours or days.I have used their screen protectors on 5 of my cameras and have not had issues with their durability on any of them. I would not hesitate to purchase their products for any future cameras
