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!

First off, I'm coming from a Microsoft Desktop 2000 which has (almost) none of the niceties this combo has. I also visited several stores with keyboard/mouse displays so I could select the right type of combo.I am a programmer and I find key size and placement to be very important! The first thing that attracted be do this combo was the height of the Esc/Function keys. Aside from being of "full" height (relatively) they are grouped and spaced well making it easy to find what you are looking for in the dark. To add, the separation between the QWERTY, Editing/Navigation, and NumPad is essential to me as I can find where the keys I'm looking for with less risk of making grave mistakes. Furthermore, the keys are located where I expect them! I can't stand keyboard that move the backslash key or insert key or use to two row enter/delete key. That kind of s*** makes programming quite frustration.The font is pleasant (trivial, I know) and I like the lowercase on non-lettered keys. Additionally, the labeling are stickers so they are considerably less likely to rub off with constant use!Some people may find the keys to be noisy but I think that it adds to the feedback. There is a slight resistance to the key which also yields feedback.The mouse could be a bit bigger but whatev... It is quite precise, comfortable, and doesn't feel cheap (neither does the keyboard).I would buy this keyboard combo again. I'll follow up in a year or so.
