Logitech MK545 Advanced Wireless Keyboard and Mouse Combo

This keyboard and mouse combo works great. No issues whatsoever.

Preface: This is a review of the keyboard only. I already own a wireless mouse (MX Master also from Logitech!) and thus set the mouse aside.Prepreface: I've owned the product for ~1 week. Thus no reliability issues so far but then again, it's only been a week.The keyboard works great!I have plenty of Logitech products and the unifying receiver was one of the big reasons why I picked a Logitech keyboard over a different brand. I was able to connect to my pre-existing unifying receiver with 0 issues.No issues at all with connectivity. I wake up in the morning, start typing, and letters show up. It just works! I've also played games on it and there's no noticeable input delay either.Ergonomically, the wrist rest is a wrist saver!However, not everything is perfect. Couple of minor cons to look out for:- The wrist rest material is a rubbery textured material. You know the type. It's going to wear off and gather grim.- There's no right windows key. I didn't know keyboards existed without the right windows key.- The top right shortcut keys. I hate them. I despise them. I can't disable them. One is a battery light indicator. Cute. 1 opens up your calculator app. Why the heck would I need a keyboard shortcut for that? 1 locks your computer. I hate hitting that. And the last one, the very top right key, is a monster. It opens up your web browser home page, using your CURRENT tab. While writing THIS review, I accidentally hit that godforsaken button and it deleted my review. It doesn't ask, there's no confirmation for leaving a form. Homepage. Watching a YouTube video and grab the corner of your keyboard to adjust it and hit the key? Homepage. Inputting numbers through the numpad and accidentally hit the key while trying to type -? Homepage. Drop everything and go directly to homepage.I'm making it a bigger deal than it should be because I'm still rating the keyboard 5 stars!

We tried a lower-priced variant for a home office setup and ended up returning it for this Logitech. The keyboard has a very satisfying tactile response, the mouse tracks perfectly, it's just no-nonsense comfort and productivity. Note that this version requires the usb dongle, no bluetooth option. One thing I observed is that certain usb hubs do cause lag with input (MacBook Pro), so if the keyboard/mouse aren't responding perfectly, try direct-connecting the usb dongle first!

Update 4/27/24:I originally rated these at 2/5 because of the manufacturer defect and some other bad first impressions. I've spent about four months with these now, and I have adjusted to the feel of them to the point where I do not feel negatively about them at all. While the defect in the mouse is ridiculous, I was equipped to repair it, and since then everything has been peaches. In fact, with this set, my tv has sort of become my primary display for all things PC. There are nicer pieces on the market, and even in Logitech's own catalogue, but these are totally serviceable for me.Original Review:Mouse arrived with a manufacturer defect. The casing was split open in a way that could’ve only happened from poor assembly. It caused the left click to not work and the mouse wheel to barely rotate. I opened the mouse and reseated the board and casing to close tightly, which seems to have fixed the issue. I imagine they would’ve replaced the mouse if I weren’t able to fix it and I’m guessing this is a pretty rare defect. Still, it really feels like when ordering a new product the first step after opening it shouldn’t be repairing it. It’s not as high quality as other Logitech items I’ve used. This is a secondary set to use while playing games on my tv. My primary mouse is a Logitech wireless I bought years ago, this set doesn’t come close to that in terms of feel. This mouse wheel feels quite cheap and has a low sensitivity, and the keys on the board are a little mushy and light for my taste. This is a secondary mouse and keyboard for my front room, and they’ll do fine for that. But I am glad this wasn’t meant to replace my primary mouse and keyboard. I have had positive experiences with Logitech items in the past, so this is a bit of a disappointment.
