Logitech ERGO K860 Wireless Ergonomic Keyboard - Split Keyboard, Wrist Rest, Natural Typing, Stain-Resistant Fabric, Bluetooth and USB Connectivity, Compatible with Windows/Mac, Black

I'm in IT - I'm at a computer all day, every day. I had a boss early in my career who had severe carpal tunnel issues and he always preached ergonomics. Due to that I've been using an ergonomic keyboard for the last 17 years, specifically the Microsoft Ergonomic 4000. That keyboard is no longer produced but I've loved it, it's held up well, and I've never had any issues with my wrists from typing all day. I recently got a new job and decided to upgrade my keyboard for the first time since 2007. The Logitech ERGO K860 came up in most searches for the best ergo keyboard in 2024 so I decided to give it a shot.I couldn't be happier with it. The shape and key placement is very similar to my beloved MSE 4000. They keys are much quieter and very pleasant to type on. I was a little concerned that the "scooped keys" in the product description would be deep divots like I've seen on some keyboards and don't care for, but I needn't have worried. These are just ever-so-slightly scooped, in a way that's barely noticeable until you focus on it, but enough that it does make a positive impact on typing.It's well constructed and feels like it'll hold up for a long time (we'll see if I can get another 17 years!). The wrist rest is really comfy, nice and wide, and not a material that seems like it will wear out or get gross over time.It connected easily to two laptops and my phone, one laptop with the USB receiver and the other two via Bluetooth. Typing is nice and responsive and I don't detect any delay with typing. I like that the function keys can be customized via the Logi Options+ app, although the default functions are pretty good right out of the box. I already had the Logi Options+ app for my MX Master 3 mouse (best mouse I've ever used!) but it wouldn't recognize the keyboard until I updated it to the latest version, not a big deal though.The only change I'd make to it is the batteries. It runs on two AAA batteries. That's fine I suppose, I do have rechargable AAAs I can use. I'd prefer that the keyboard be USB rechargeable like the MX Master 3 mouse - charge it once every few months and then don't worry about it. Now when the batteries on this keyboard run low I'll have to go searching for batteries to replace them instead of just plugging it in for a bit. Not my favorite, but it's not huge deal.Overall incredibly happy with this keyboard! It's definitely a good successor to my Microsoft Ergonomic 4000!

UPDATE 2 (7 Aug 2021, ~7 months into ownership).I found the Microsoft context-sensitive menu pop-up key -- equivalent to the right mouse button -- of the MS EP4000. See picture. I don't love this location. But at least it exists. I'm moderately used to it's weird inaccessible placement. But I do have to always look to find it, instead of knowing it's location by muscle memory, like most keys. I probably should put one of those raised gummy circles (like on my delete key and fn key here in the pic) on it.Also, I like this keyboard now so much that I bought one for the office too. It's outside office standards, so I paid for it myself. (This really helps avoid the constant disorientation of working on two different keyboard between home and work.)UPDATE (7 Apr 2021, a few months into ownership).The problems I wrote about below, seem to have miraculously evaporated. I have no idea why. Now this keyboard only spams the volume-up (or down) signal to my PC maybe once a month. And I’ve found that just taking the USB fob out for a second, and cycling the power button on the keyboard clears that every time, and takes maybe 5 second. For something that happens maybe once a month, I can live with it. It is otherwise a very comfortable, fast, easy, quiet keyboard. I’ve even become accustomed to toggling between F-keys and media keys. All in all, this is my new favorite keyboard.ORIGINAL REVIEWThis seems the best option for users who loved their Microsoft Ergonomic Pro 4000. Same split layout, and the other keys are more nearly where muscle memory expects them to be (INS, Home, pg up, DEL, end, pg down). And the key action is awesome: actually way faster than the MS EP4000. ... BUT:WARNING #1:Around 1-4 times a week, the communication between my PC and this keyboard locks in some weird setting, like increasing the volume. I can unintentionally get max volume this way in <1 second, with zero forewarning. Happens when I haven't even touched the associated media key.At that time, no other inputs are possible, since the keyboard is busy spamming that one keystroke to the PC. The only solution is (after ripping my headphones off) to remove the USB fob from my PC, wait a minute, plug it back, and hope for the best.Usually that works. But sometimes it's just more of the same, and I have to manually restart my PC. At least that (a reset) always fixes it. But it's a terrible interruption to workflow. You can lose important work that way!This happens on both my self-built PC (keyboard drivers installed), and on my HP laptop (keyboard drivers not installed). So, it's not a problem with my PC. It's not a mechanical sticking (no key is physically wedged): it's a logical sticking.To be clear, it's not just "volume up" that gets locked active. Other keys too. Volume down. And toggles between apps. And stuff I can't really explain/describe: I just see a lot of fibrillation on my monitor, as the various apps go nuts - so far without editing content, but long term who knows?I should RMA this keyboard, but the key action is so damn fluid - I type a lot faster on it - that I'm dragging my feet on the RMA. That, and it's otherwise the prefect replacement for my beloved Microsoft Ergonmic Pro 4000.WARNING #2:I HATE that I have to toggle between the F-keys between F-functions and media key functions. I am not used to that. My old keyboard -- like many who buy this, I bet -- was a Microsoft Ergonmonic Pro 4000 (before Microsoft ruined that line with their terrible 7000 update). It had physically distinct media keys vs. F-keys. So I'm used to adjusting sound volume instinctively, without thinking about it, and ditto hitting F2 to edit a cell entry (e.g., in Excel), or hit F11 to enlarge my browser (to remove navigation bar shrubbery). But on this Little Compromise of a keyboard, I have to constantly recover from hitting an F-key/media with the toggle set to the wrong usage. Aarg!I am slowly learning to press the F/media key toggle, while watching my monitor for the brief flash that tells which mode it's in, then deciding whether to repress the F/media key toggle again, before trying to get either an F-key or a media key to perform some function. I'm Not loving that!I would REALLY prefer a keyboard set-up like the MS Ergonomic Pro 4000, but that is probably tied up in a patent, that MS won't release or reasonably license, but neither will they manufacture them anymore. Oh, you may still find one on eBay, used, for $300. Ugh.WARNING #3:The Microsoft context-sensitive menu pop-up key -- equivalent to the right mouse button -- of the MS EP4000, is missing. Replaced by a second key: "opt/ctrl". You'd think the driver software would let you program this key to do different things. I have not found how to make it act like the awesome key that it replaced (the Microsoft context-sensitive pop-up menu key). I'm still mourning the loss of that little key of wonder. Slows me way down to have to take hands off keyboard to fiddle around to right-mouse click every time.

Although this was super pricey. I can't knock that it definitely made a difference with my wrist pain. I work on the computer up to 10 hours a day, most days. Monday-Friday and although I still get normal aches. It's not like the pain I used to have. I would definitely recommend. I bought this with rechargeable AAA batteries. There's never any lag and the Bluetooth seems like it works fine. Although I'm never farther then arm length from the computer it seems durable and it was easy to use. It's pretty big compared to the other keyboard I hd but it's morales normal for an ergonomic keyboard. It does such it doesn't light up that was what I was indecisive with buying this one and board that lights up. Bit I do not regret this buy.
