Genuine 1RW52 KB522 X20M8 7VHY1 Dell Business Multimedia USB Wired 104-Key 14-Hot Keys 2 USB Hub Keyboard Compatible Part Numbers: 1RW52, KB522, X20M8, 7VHY1

Fifteen years ago, I bought two Dell 390 systems and a Dell SK-8135 multimedia keyboard. It lasted me through the Dell 390s, a T7500, and now a T7910.Last week the SK-8135 keyboard started to die. The internal two port USB 2.0 hub stopped working. I decided to buy a new keyboard and according to Dell the KB522 is the follow-on to the SK-8135. The KB522 is a true SK-8135 replacement. It has the multimedia keys, volume control, 104 keys, plus a two port USB 2.0 hub.Yes, the keys on my SK-8135 were still working after fifteen years. I suspect they’re working for two reasons. First, Dell made a great product. Second, I put a keyboard cover on the SK-8135 around thirteen years ago. While the cover got really grimy and dirty, the keyboard and inside the keyboard remained clean and working. The keys never gave me a problem.Cleaning the SK-8135 or the KB522 and their cover was as simple as turning off the system, unplugging the keyboard, and running a soft, wet towel gently over the covers / keyboards.On the SK-8135, the cover started to become a little difficult to see through. The clear plastic was starting to yellow (but only slightly). Finally, the cover was becoming slightly loose around the keys were becoming difficult to see at an angle. These issues were not enough by themselves or together for me to retire the SK-8135, but add in the hub stopped working and it was time to say nighty, night to the SK-8135 and its cover.As Dell said the KB522 was the SK-89135 successor, I bought one and its cover. I used the KB522 by itself (e.g., without a cover) for around three hours, a restart, and two shutdown, and power ones. This usage gave me to confidence that it was OK to install the cover.Installation of the keyboard is straightforward and easy to complete. I dislike installing screen protectors and usually take them to uBreakIFix for installation. (At least the local one will do it for free if you bring in the screen protector and have Asurion Home Protection.) Unlike tablet or cell phone screen protectors I found installing both the cover for the SK-8135 and KB522 to be easy! I fit the keyboard cover on tightly, flipped over the keyboard, removed and attached each glue cover individually, and I was done.I'm including four photos. They are:1) The KB522 without the cover (top).2) This product (the KB522 cover).3) The KB522 with the cover installed (bottom).4) The KB522 with the cover installed (top).As you can see the keys are clear. I'm typing this review on the KB522 with the cover without any issue. Of course, your mileage may vary, but I find this keyboard and cover to be wonderful.I can highly recommend both the KB522 and its cover. Five stars to both. I FULLY expect this keyboard and cover to last me another fifteen year. Here is hoping I, at 65, will last longer than this keyboard and cover.

I spent literally hours reading customer reviews of the many less expensive keyboards that are sold at Amazon. In years past I have bought good standard keyboards live at various brick and mortar electronics stores for $25 and less. I ended up coming back to the customer reviews on this one repeatedly--in between reading about others--and ended up buying this one.I agree with others having said that this is more of a high profile keyboard than the lesser expensive ones that are now being sold. High versus low profile refers to the travel distance necessary to press a key and get the response. It also refers to the pressing of the keys having a "feel"--a perceptible resistance of some sort--and a definite click. One reviewer said this is a medium profile keyboard as opposed to a low profile keyboard.I have also managed to use two strange low profile keyboards in more recent years. The fact that this is *not* a low profile keyboard matters a lot to me. The keys have a definite "feel"--some small but definite resistance, and a definite unmistakable click. I have been enjoying it for a few hours now.I also appreciate the fact that the keys are all in the right places with nothing squeezed and with no little keys labeled "Fn." I had gotten used to using a strange keyboard with the "Home" key nearest to the "Backspace" key, to the right. I have no doubt that I will soon become accustomed to the "Insert" key being back in place there where it belongs with the "Home" and "End" keys being not too far away. The latter are the two in the middle vertical row of the group of six keys that includes "Insert," "Delete," "Home," "End," "Page Up," and "Page Down." I also like that the little raised finger placement marks are where they belong for touch typing, at the bottom edges of the "F" and "J" keys.I am a big old man with a bit of a leg problem. To sit comfortably for hours, even discontinuously, requires my legs to be up on a stool. For years I have typed with my legs up and with my keyboard resting on my thighs. I decided to spend a bit of time placing this keyboard the best way possible for my use. I am using the included wrist (or palm) rest *not* to rest my wrists upon but to make the base of the keyboard larger and hence more stable on my lap. And I now have a magazine folded in half and taped to the underside under the top so that the keyboard is actually flat on my lap rather than tapered downward toward my feet. The numeric keypad sticks out to the right as it should. It works!I did not buy this for the USB ports and have not tested them. Other reviewers have discussed the USB ports rather extensively.The pause/play hotkey, the track back and forward hotkeys, and the volume wheel--some of those in the separate top row--work with my free Foobar2000 music player and with my free MPC-HV video player. Yaay for compatibility!Speaking of compatibility, as one might expect this keyboard is working fine plugged into a little 2009 ASUS Seashell netbook--with added memory and with a wireless mouse and a big external monitor. I expect it would work with any computer running any version of Microsoft Windows, new or old.

My goal was to find a keyboard that was:1) full-size with numpad2) slim profile, lightweight and easy to slide around as I adjust my sitting position often at my desk3) built-in palm rest that I don't have to buy separately AND physically attaches to the keyboard so they move together4) Relatively cheap, no RGB and other gamer marketing upsell nonsenseThat last one was a factor because almost everything that meets points 1, 2 and 3 is a brandname "gamer" keyboard with rgb lighting and thus the inflated price tag that tends to go with over-designed, over-priced gaming peripherals.This keyboard hit all the marks beautifully. Also while it's not my first keyboard with a volume control dial, for some reason in the past I never used them, but I find myself using the wheel on this one all the time. I regularly play games with this (multiplayer/fast paced included) and it's been perfectly fine.The key height is medium profile, not as high as a mechanical keyboard but not too flat like Apple ones. I find it comfortable to type on and more than tactile enough to always be able to find my place by touch alone without having to look down (which can't be said for those super flat keyboards).The palm rest is of sturdy quality given the price, in fact far better than my previous, 3x more expensive keyboard's palm rest, which had already started to warp and break after only a couple months of use.
