I'm writing this five-star review after having endured a failed one-star attempt to install this Screen Protector (SP.) I replied candidly when a customer service rep subsequently e-mailed me to ask if I had received and successfully installed the product. In her initial message, she explained all the things I should have done but, unfortunately, didn't know about. She promptly sent me not one but two SPs to replace the one I had purchased and thrown in the trash. She mailed me again shortly after I received and successfully installed one of them. Using the tips she provided and a few others I picked up on the Web, the job proved to be relatively easy and straightforward. She asked me to share my final approach with others who may have experienced the same frustration I initially did. So, in recognition of her outstanding customer service, here goes.At the risk of stating the obvious, the entire process is best accomplished in a dust-free environment... like a closed-door bathroom made humid by the shower you just took. Start by cleaning your camera's screen. You may need to use a solvent to remove any traces of dirt or oil. To remove any remaining dust particles, wipe the screen with the microfiber patch the vendor provides. Next, cover the entire screen with (blue) Painter's Tape. This stuff doesn't leave any residue when removed. Apply a length of tape to both the left and right edges of the screen. Carefully align the outer edge of the tape with the edge of the screen. Take your time here. It's important to be precise. Let the tape extend beyond the upper and lower edges of the screen. Now apply tape along top and bottom edges. The ends of these tape strips should fall onto the strips applied to the left and right sides of the screen. Again, be careful to align the outer edges of the tape with the edges of the screen. At this point, you should be able to see all four edges of the screen, albeit indirectly.Next, apply a length of Painter's Tape to the Screen Protector on the edge opposite the one containing the "Step 1" and "Step 2" tabs. Place approximately half the tape's width to the edge of the SP. This is the "hinge" that will hopefully prove to be invaluable. Trim the ends of the tape with a scissors, being careful not to cut into the SP. There's no need to get extremely close here. Now place the SP onto the taped-up screen. The Expert Shield is an extremely precise fit to the 3" screen of my new Panasonic ZS70 camera. Align the edges of the SP with the edges of the screen as revealed by your carefully aligned strips of Painter's tape. Now press the still-sticky end of the hinge against your camera, around the end and down the side. Then, using one of the "Step" tabs, lift the SP then lower it to the screen again. It should drop precisely into place. Try it a couple of times to make certain all is well in never-never land.Now comes the exciting part. Lift the SP once again and hold it out of the way while you use your other hand to remove the Painter's Tape on the screen. Pull it from the upper left corner to the bottom right corner. It should come off as a unit in a matter of seconds. The tape should remove any dust particles that may have fallen on the screen before you completed its application. Now, for the first time, expose the sticky side of the SP by peeling off the protective "Step 1" layer. Quickly but carefully and gently lower the SP to the screen. It should drop into place perfectly aligned. If so, wrap one of your index fingers around the vendor-provided microfiber patch and press the SP into place... not too firmly at this point. I started at the hinge side and moved slowly toward the "Step 2" tab. When done with this step, remove the hinge, being careful not to shift the position of the SP. At this point, you can apply increasingly greater pressure to the SP to remove any bubbles that appear, despite your best efforts to preclude their unwelcome arrival. I had a couple of them that took almost five seconds to remove.Hope this helps. With any luck at all, it should reduce the number of one-star reviews I've read so often.
