Bests & Worsts Reviews from Amazon

UPDATE AND ADDITIONAL DETAILS AT BOTTOM. Cover was easy to install: took about 10 minutes with very little struggle, included guide was perfect. Even without turning up touch sensitivity I found responsiveness to be very good. However, it has many downsides. -Black frame is slightly too small and obscures screen edges, especially corners; it is not terrible, but with so many other affordable options there is no reason to put up with this; product images seem to show a small amount of bezel showing under the black edge but this is not the case, you will not see any of the phone's bezel -Rainbowing (a.k.a. Newton Rings) are a normal part of having two pieces of glass touching; if quality of the cover was higher (and more expensive) this might not happen but seller should mention it to customers - only way to avoid would be full screen adhesive which would make installation trickier, too; the effect is especially present where the screen curves and must touch the protector -Edge adhesive is not consistent all the way around; if a drop of liquid touches an edge (especially along the sides where the adhesive line is thinner) it will get sucked under the screen protector due to capillary action; only way to get it out is to lift protector off and compromising the adherence of the protector (allowing it to dry could leave mineral deposits rubbing between the screen and protector) -May be better for some users depending on what phone case they are using, but with the slim case I use there are 2-3mm portions of exposed screen along the edges; corners are particularly vulnerable (did not deduct stars on this point because it may work well with a bulkier case) This protector is barely worth it. Ease of install was the only major plus. UPDATE: Happy to be contacted by seller, will gladly update review when replacement arrives. UPDATE: -Replacement protector has tolerances even better than the very close match it was before: speaker cut out is a perfect fit, black outlines are almost indistinguishable from the bezel. I am actually quite impressed by how tight the tolerances are on the replacement. The newer protector also solved the problem of the old protector corners obscuring a tiny but significant portion of the screen. -The edge adhesive seems more consistent this time around, however I would still avoid contact with liquids in case they infiltrate the edge and force you to remove the protector. That said, I have not tested how it would perform if submerged or splashed. -Installation was still a breeze, especially considering how finicky full-adhesive screen protectors are. Still, be extremely rigorous about dust and specks before you install. The dry wipe included in the package seemed to release its own fibers as well. Removing the cover later will compromise the very thin adhesive lines. Also, because it is not completely adhered you get a trade off: Rainbowing. -Rainbowing is interestingly both better and worse: worse because it occupies a larger portion of the screen than the last protector; better because it is less noticeable overall and seems reliant on the type of lighting. Under most situations it is very difficult to see the rainbowing although it is definitely there at certain angles (usually angles in which you would not be using the phone anyway). However, I have a particular room in my home that uses a combination of warm and cool fluorescent light bulbs that seems to bring out the rainbow effect. Attached image shows effect, but again it is practically invisible 95% of the time. -The dot matrix of the screen also seems to be more visible under certain lighting conditions, but I could not pinpoint them. This never happened when I was actually using the phone so it is of negligible effect. -GearVR: I am happy to report that the screen cover does not appear to affect the quality images when used in a GearVR. The fit is a bit tighter but not a problem. UPDATE: spoke too soon, the dot matrix on the protector can be seen warping/magnifying pixels, especially in large single color areas with no motion. Also, when there is a large amount of contrast (white on black, for example), the lighter colors appear to "bleed" and appear as a halo, which is the reflection of the lighter areas off the protector. These issues are situational but are noticeable, perhaps even unbearable since the Note 9 is the ideal phone for GearVR. Since GearVR is probably not a general-use case I am not deducting stars. -Cooling: I am trying to keep the phone for as long as possible so am very conscious of the need to keep the phone as close to room temperature as possible. As most would probably guess, the screen protector has a negligible affect according to 3C Battery Monitor. -I am a sucker for good customer service, they definitely stand by their product and want it to be the best for their users. I give the product itself 4 stars due to the rainbow effect (which is possibly unavoidable with any edge-adhered screen protector), but add a star for proactively assuring customer satisfaction.
