Nice action, quiet, feels heavy and well made, mouse is nice and smooth, looks great, long battery life.

Nothing yet

This keyboard has a very nice feel to the keys. They don't make a bunch of noise and seem to react quite well. The wrist rest is also cool. As far as the Mouse it is real good as well. One reviewer complained there was no calculator key. It's fn and page up together and the calculator pops up.

Looks nice

Only instructions are on the inside lid. Did exactly what it said, but wouldn’t recognize the keyboard. Not using it for anything else except my desktop. Didn’t have prob with Logi before. Wizard had no options for unify, and if the keyboard doesn’t work,,how can I download anything from their site? U have to be able to type in your search engine. I tried for 4 hours, so I ended up getting a refund. Extremely disappointed, to say the least.

This was for usb only, not Bluetooth

I have a work computer and personal computer on the same desk. It's great to be able to use one keyboard and mouse for both computers.

The keyboard Bluetooth is good, but the mouse seems to have some issues connecting to the computer consistently over Bluetooth. To work around this, I connect my mouse to my computer using the usb unifying receiver.

This keyboard is definitely worth the money.

- Switch between multiple Logitech Unify points as required (if you need more than 3... well, that may be a problem) - Ergonomic / Comfortable - Soft, quiet Keys - Sturdy Construction

- Large Mouse - White underbody, weird in comparing the last two sets of Logitech combo sets that were all a black - Miss the dedicated multimedia / calculator keys, function keys are just not the same

So I bought this as an upgrade to my Logitech MK700 that was slowly dying a slow death (mouse clicker in particular was double clicking quite frequently) and i needed something to replace that. As a bonus, this combo set has up to 3 distinct computers, which i have set for my work's similar Logitech system, so when i come home I just have to switch my MK850 to "2" and i can use my work laptop without actually having to physically pulling my receiver from my PC and plug it into my Laptop. Since i did on occasion leave my receiver at either work or home it is a great upgrade in that sense. As well, this keyboard/mouse combo is of a higher quality, it just feels better than the MK700, with the membrane switches being soft/quiet but still tactile. Wrist rest is a good upgrade, but still nothing compared to a dedicated one or something found on a more premium mechanical keyboard, for what this is, the value can't be beat.

Comfort, convenience ease of use and did I say comfort. The mouse Click wheel is weighted, so it works better, the keys are balanced to give the propper feedback. The wrist rest is uber comfy... like a dream. the Wave in the Keyboard helps immensely. even the feel of the keys on your fingers. Oh HEAVEN... not exaggerating. it's very comfortable

None yet. but I'm easy to please

I am very excited to take the time to rate this item 5 out of 5 stars. So comfortable, so well built, such fine feedback. Truly the Mercedes Benz of Keyboard combos. WORTH the MONEY... Like a comfortable pair of shoes that also look great. I am 10-10 happy to have this thing. I could type forever.. and not say anything. AHHH

Works excellent, have it paired through USB to a laptop and Bluetooth to a smart phone. Switching between devices is excellent. even though not mentioned, mouse has 4 ways scrolling and has a button to turn on / off tactile scrolling or smooth scrolling for the wheel. Keyboard is quiet with good feedback.
