Keyboard Cover Compatible with Logitech K350 MK550 MK570 Wireless Wave Keyboard Accessories.MK550 Keyboard Protector Skin Black.

UPDATEI LOVE this cover. I can hardly tell after a few months of use that it's separate from the keyboard,except when my fan swings by and flaps the end up -- a strip of tape takes care of it. The black on the keys is starting to fade, but it's interesting to see what keys you use the most, but it works fine. More than of this, though, is that I've found this allows me to use less pressure on the keys. The cover itself does some of the work, and it has almost an ergonomic laptop feel to it. With arthritis in my fingers and hands, this makes all the difference in the world when you type. I do have some issue with the page up and down buttons -- sometimes I hit one and the other one is activated, but since I primarily use the main keys and very few of the "extracurricular" keys (I have no idea what they're called), I'm not too concerned. I definitely recommend this for any K350 users, and will by again.Original 5/21/21Just got this today. Immediately pulled it out and thought... oh, no way this will work. But it fits my Logitech K350 perfect. I wish I had purchased the sheer one instead of the one with the black keys imprint ... can't see the location of the actual keys... but if the cover is positioned correctly, it's fine. There is some adjustment getting use to the 'feel' of the impact. Some of the keys have more of a gap between the key and the cover, and you can feel yourself pressing air. And there is some shifting of the cover especially when you reach with your forefinger on the bottom keys, but with the right pressure, you'll hit the keys you're supposed to. I through 1 keyboard every 9 to 12 months, and I live at the computer, so only time will tell if this adds any longevity to it, but I do feel easier about drinking and snacking having something protecting the innards as I work. I'll update this review after a few months of use.

I love my K350 wave keyboard, but it was terribly noisy. Trying to train over the phone while taking typed notes was nearly impossible due to the noise. I've had this cover on my keyboard for almost 8 hours now and am astounded by the difference!To address some concerns I read in reviews before I ordered:- The cover went on easily; I used a paperclip to settle it more closely in a couple of spots.- The "black" cover is sheer except for the printing over the keys themselves, which allows me to still see the edges of the F keys to know which is which (I rarely use the F keys).- I am a touch-typist, so the home key nubs are great and I'm not worried at all about the print wearing off. The only issue I've had so far is needing to press the "back" key a little more directly than usual. Apparently my reach for it is off-center, and it doesn't always depress the way it used to. A tiny adjustment to make in the grand scheme of things.- The tactile element is perfect for me, I like the "softer touch" feel. However, it could be annoying for some.

Bought to cover keys of Logitech K350, and it fit perfectly. It comes in a long envelope, folded in half over thin cardboard. You have to open it and slightly stretch it over the keyboard. Installing it in place takes seconds, and it lays on top without any adhesion.You can easily remove this cover for cleaning. One word of caution during COVID, don't use alcohol to clean the surface, because it takes off the lettering and paints on the vinyl/rubber keys. I learned that the hard way. It is best to use soap and water, or if getting rid of crumbs, to use the canned air like you would on a regular keyboard. After washing, you can hang it to dry, or simply wipe it down with a lint-free cloth. Don't use paper towels, or you will end up leaving behind paper dust residue. Learned that lesson the hard way too.I would recommend this product for Logitech's K350 keyboard.

A few things to note:- Fit- Feel- Look- CleanThe fit is mostly perfect. I have 3 of these keyboards and got this+keys for my father. It is designed very well to fit the board, and while one of my keyboard+cover combos has a few slight waves to it, with a material this thin, I can understand production making a few errors or that the keyboard creation isnt perfect every single time. No major deal as it sticks to the device well. The only downside to the fit is a few places where the material is barely too big or how the bottom of it doesnt quite fit along the line cleanly, leaving the crevice to still be affected by inevitable dust and moisture. Truly minor in the grand scheme of things and the only actual flaws.Feel perhaps varies per person, with day one feeling extremely weird (like sitting on a couch covered in plastic for the first time), but now feels completrly natural and good on the fingers, it also adds a level of muddling to otherwise loud-clacking keys. This was a very welcome surprise I never considered, and am most grateful for. Cant be without it now, just for that. Membrane is thin and while some instances of fit might make their presence known, I would not call it a detriment or negative in any way.It looks pretty good, too, all things considered. Another instance of weird at first but it settles quickly. The slick plastic at the media and calculator/power buttons can become more distinct if one rubs around the shell, and theres something satisfying for me in spreading the air bubbles around when on the phone. The gray/grey buttons are given a black background which keeps to thr easthetic of the cover, but not the keyboard as the zoom buttons are not entirely covered. Im not sure how I feel about it, as its not bad amd makes them easier to identify, but a part of me wishes they were gray/grey. Some button labels, such as the volume buttons, are not centered over the buttons and can be apparent if paying attention, but ultimately not a big deal to me. Also worth nothing this keyboard displays F1-F12 on the side of the keys, and no labels are provided for this, leaving the original keyboard markings to view through the transparent cover.Cleaning-wise, I havent tried it and dont intend to unless necessary, and will update if/when applicable, but the ease of handling and quality of material suggests it will be a cinch. Very thin but strong feel, unless there's a hole or few I cant see, I feel confident in its purpose. The membrane is raised where the keys are so any spill will not only not enter your keyboard but have an elevated path away from the keys. This means the wrist-rest and immediate surrounding areas of the keyboard become thr most vulnerable points, so keep in mind what else nearby needs protecting.Couldnt recommend more.
