Bests & Worsts Reviews from Amazon

Well, I'm mighty impressed. I really didn't think they'd be all that great (I actually ordered other kinds so that I can compare them). I was concerned before ordering that the sliding cover would slide too easily with movement and/or fall off at some point. Mind you, I literally JUST installed this thing on my laptop (Dell XPS) so this is not a a review based on longevity of the product; Merely my initial impressions. Installation was a breeze. They give you small, clear adhesive strips so that you have better control during placement rather that using your fingers on this TINY doohickey (see photos). The cover does not slide with typical device movement and takes just a wee bit forceful pressure to move vs just touching it (see video for demo). I don't know if it will loosen over time or if the adhesive will fail, so I do plan to update after a period of use. It also looks as though there is a lip on the rim of the adhered piece that will keep the cover from falling off. Yay! Unlike my old (janky) sticky note cover, this thing completely blocks the outside light and gives a black screen when the camera is covered (see photos). My laptop screen also lays almost completely flat when closed, so I needed something very thin to ensure no screen damage when closed- this is as close to perfect as you'll get in terms of thickness (see photo). So far, I'm very happy. Once I am confident that it will pass the test of time, I plan to apply the second one to my Samsung Galaxy s9 (I already know that it will fit, even with my cover on). Here's to hoping!
