Logitech K845 Mechanical Illuminated Keyboard, Strong Adjustable Tilt Legs, Full Size, Aluminum Top Case, 104 Keys, USB Corded, Windows (TTC Red Switches)

I gave this keyboard 5 stars because it is well built, does the job fine and satisfies all my needs. But ideally Keychron would make a keyboard specifically for Windows (they provide replacement keys for Option->Windows and Command->Alt, but they don't for PrintScreen, ScrollLock and PauseBreak. And even though I rarely use those keys, it would bother me not having them properly labeled).I'm typing this review on the Keychron C2 Full Size Wired Mechanical Keyboard for Mac, which also uses red switches, and I like it more in several ways. The keys make a nicer, softer sound than the Logitech's keys. And the secondary functions of the F keys (like media/volume controls) are backlit, which they aren't on the Logitech. Though that's not a big deal because I only use Volume Down (Fn+F10) and Volume Up (Fn+F11).Also the Keychron's NumLock and CapsLock LED indicators are a nice, soft blue color, whereas the Logitech uses very bright, white LEDs (they are so bright & distracting that I covered most of them in black tape). And the Keychron has some nice touches like different colors for the letters & numbers vs. all the other keys, and a nice effect where the LED of each key slowly fades out and back in whenever you press them.So if the lack of proper labeling for the PrintScreen, ScrollLock and PauseBreak keys doesn't bother you, I recommend the Keychron over this keyboard.

I have now been using this keyboard for a little over 1 week. So far so good.My previous keyboard was a HyperX Alloy Elite with blue switches so this keyboard is a bit of a downgrade. Even though this is a full-size keyboard. it takes up less space on my desk compared to my old one which is a plus. The TTC browns have been a pleasure to use although I did have to get used to them as I was coming from a Cherry MX Blue switch. The keys have a high actuation point so there is a faster responsiveness than what I had previously. The keys also feel much lighter. When I first received the keyboard, I had to double-check the packaging to make sure I didn't get send a red switch because at first it was very difficult to feel the tactile feedback. However, after typing on the keyboard for a while I can feel it just fine.Overall pros and cons:Pros:1. Compact but full-size2. No fancy bells and whistles3. Backlighting is fantastic4. Very sturdy with quality construction and materials5. Keys are lightweight with a nice feel to them. Reminds me of the Dell keyboards so many of us used back around 2000-2010 era. The design itself is reminicent.Cons:1. Wish it came with a wrist wrest - I can't be too upset given the price point but I will definitely need a wrist wrest sooner than later2. This keyboard might be better for gaming than typing (it is marketed as a gaming keyboard) but for those of you who are strictly typists and not doing any gaming, you might look for a slightly heavier brown switch or look towards to TTC Blue switch model.3. Even though these are TTC Browns there is still a small, subtle, audible click while typing which I find to be fantastic. To me personally, it's a great balance that I wasn't expecting. Just forwarning.4. The keyboard doesn't have an onboard memory. If you take the keyboard from one computer to the next, it will not remember the lighting settings. It is rather easy to change the lighting, as all you need to do is hold FN & select F12. Takes about 5 seconds.

Life with the new keyboard is really awesome. I mean, I loved my Logitech G510, but it died after many long years of good service.I wasn't sure the keyboard would work, since it wasn't shipped as I would have expected. It was like someone took the keyboard off the shelf (in the product box) and slapped a shipping label on it. No outer packaging and protection other than how the manufacturer boxed it.I do more office related work at home these days and less gaming that requires the cool features and bells and whistles, and wanted to go to the mechanical keyboards for efficience with typing.I like the feel of the keys beneath my fingers, perfectly spaced for fast typing without having to pound the keys. The simple backlighting is perfect as well. No frills, just a simple efficient white light. The characters on the keys are unimportant to me as I don't look at the keys when I type, BUT... looking at the keyboard, I find the "font" of the key characters to be perfectly readable and very attractive looking.As for the "quietness" of the keys, it would depend on your definition of quiet. I chose the red because I'm a fast typist and like the smoothness of flow, so rather than going for the brown and quiet, I'm satisfied with my choice. The sound of the keys is not much louder than my old keyboard.Since I always use a wrist pad regardless of the keyboard, there was no adjustment to the height of the keyboard, which I actually found not as high as many complain that it is. I can use it comfortably without a wrist pad.I've had no issues with the lighting -- yet. So far so good. I couldn't see where to adjust the lighting. It didn't come with a manual so I had to go to the Logitech site to get that information. Not a biggie.For the price? It's well worth it.UPDATE: October 18, 2021. I noticed for the first time this morning when cleaning off my desk that the "M" key and the "ALT" key no longer light up. In fact the text is now dark gray. Not a big deal for me, since I don't need to look at the keyboard to type. I suppose this is what typing 95 wpm does to the keyboard. I'm still loving the keyboard and would definitely recommend!UPDATE: January 26, 2021. I've got a couple of keys that have "died". That is, they still work, but the key itself feels "dead" and you have to pound it with your finger harder to make it type out the letter. I'm going to be doing a good cleaning this weekend and hopefully that will help. Otherwise, I'll be reaching out to the manufacturer on this issue.
