Logitech K840 Mechanical Keyboard with Romer G Mechanical Switches for PC - 920-008350 (Renewed)

I bought this one Logitech K840 for myself, but got two more for work, one for myself there and one for a colleague there. This review is for the "Renewed" or pre-purchased, returned, and re-purchased Logitech K840 on Amazon. I'm not sure the used "Amazon Renewed" K840s are still available, but the brand new ones are only $10 more. I'm a sysadmin and type all day long, but I'm not a gamer at all. If you need a gamer POV on this keyboard you won't get that here.The Logitech K840 with its Romer-G keyswitches is a great work keyboard that will make you happy. The Romer-G's have less key-travel before actuation, which allows you to type more quickly and with less effort then you'd need for a similar typing-rate on, say, a Das Keyboard with Cherry blue switches. The Romer-G's are slightly less noisy than Cherry-Blue switches. If you don't bottom-out the keycaps they can be MUCH less noisy.Of the three "Amazon Renewed" pre-used Logitech K840s I caused to be purchased over the last year, two are still working. The one that failed had its Ctrl-key stop mysteriously after several months of use. Since the purchase was made through an intermediary I didn't do a return--I wasn't sure if I had purchased the K840 or if my intermediary had done the purchase, so there wasn't really enough information to do a return. The failure will not prevent me from buying another (used) K840 though, as they're so inexpensive for what they are, that I won't feel bad about getting another. A Das-Keyboard with blue switches is $120 and a WASD **open box** CODE 104-blue-key keyboard is $140, so a brand-new K840 is less than half those prices.If you need backlit keys or colors or other gaming-kiddie related stuff, this is not the keyboard for you. This is just a NORMAL USB KEYBOARD with very nice switches. The switches are noisier than a dome-keyboard, so if you're in a cube-farm right next to someone else, your neighbors might not like it. But those are the only two reasons NOT to get this fine piece of hardware. Give it a try! You might discover something wonderful, as I did.Thanks all for reading.

Ordered my Logitech K840 Keyboard (refurbished) on 10/25/2019 and was mostly thrilled when I plugged it in. My only gripe is the lack of a caps lock light. Small thing but annoying at times. I don't do much gaming and this beast was going to the office. I'm a keyboard shortcut fanatic so these mechanical switched were wonderful. It's my first one and I chose this keyboard as it should be a little quieter than some, not disturbing my office mates.It came home with me when Covid started and worked for a while, then around the end of 2020 I started having trouble with the ALT key. Swapped keyboards to check it wasn't the computer. I wasn't always registering when I hit the left ALT key. Looked up the keyboard and saw that the brand new ones have a one year warranty so the refurbished couldn't be longer so it wasn't worth digging into to see exactly how long that warranty is. At work I'd used a membrane keyboard for 3 years after the one that came with my cube wore out. Expected much longer life from a mechanical keyboard and I figure even my use of shortcuts is nothing compared to what gamers put their keyoards through.Maybe there was a bad batch of switches and I just got unlucky. Not sure I'll buy such an inexpensive one to replace it. although it's tough to find one with the features I need for office work, especially the context-sensitive menu key. So few mechanical keyboards have it.I still think Logitech is very high quality and don't think Romer switches suck because I had a bad experience. I think it probably was just some bad ones. If it held up for 5+ years it would have been great.

I started a new job and preferred to have something a bit more to my liking than the Apple Wired Keyboard I was supplied and at a low price since I would need to supply it myself. I opted for a quieter board then the MX Cherry Blue switches I am used to at home. I work in an open office setting where loud clicking is not polite.The Romer G switches offer a nice level of tactile support. Typing on the board for most of the day has been a very pleasant experience. Travel is good, while actuation is minimal and snappy. While less precise in feel then a Cherry MX switch, the Romer G's provide a quiet experience superior to any rubber dome switch I have used. There is a small level of lateral wobble in the keys, but nothing out of ordinary. The chassis is a metal top plate with a plastic under cover. This gives the board a nice heft that feels solid on my desk. There is minimal to zero chassis flex.The lettering on the keys are applied as decals and the plastic of the keys themselves, while a pleasant to the touch matte texture, will surely hold onto oil in the long run. I will have to see how it appears over the next few month.For $40 dollars however, there are few options as good as this one. I would have appreciated a detachable cord, but since the likelihood of this board leaving my work desk is low, it is a minimal concern. Although a reconditioned product, the appearance is excellent without any noticeable blemishes. The aesthetic pairs well with the apple products I am workin on.If my impressions change over the next few months I will be sure to update this review.
