Logitech MX900 Performance Premium Backlit Keyboard and MX Master Mouse Combo , Black

AWESOME keyboard and mouse! (Any type-o's in this review are due to my fat fingers and not the keyboard ;)Probably unlike most reading this review, I have this combo running on a Linux (Centos 6.6) machine (which I believe has a Tyan motherboard, fwiw). I was a little concerned having read some of the other reviews. Not that it wouldn't work eventually, but that I would have to hunt down a script or scripts in order to get it to work smoothly. In particular, it looked like people were able to get the first device working but getting the Unifying Receiver to find the second device (the mouse) was not working out of the box.This was not the case at all with me. Half thinking it wasn't going to work, I shut down my machine, plugged the Unifying Receiver and restarted. It worked! Period. Both devices were identified and functional. The speaker volume was controlled by the volume keys. The F8 key put my system into sleep mode (hibernate) which is exactly what I want it to do while I'm asleep or at work. I probably don't use all of the features of the mouse but the left, right, forward, and back buttons work. I haven't found anything yet that uses the "application" button. I'm not actually sure what it is supposed to do. Is it supposed to let me switch between apps like the F4 key? It doesn't appear to do that. Then again I haven't totally figured out the F4 key's use either. That appears to let me switch between the app I'm using and I guess the previous one that had focus? Meh.I should be able to zoom by just using the mouse and a mouse button combination but that is not working for me out of the box. Instead, I zoom in and out using the scroll wheel while holding down the control key. I'm guessing I could load some software to get the zoom working with just the mouse but I just don't have a problem using the CTL key. The panning by scroll wheel also worked as expected though.I was already using a wireless keyboard/mouse combination (Microsoft) and it took all of 10 seconds to realize the Logitech hardware was light years ahead of that cheap feeling thing. It feels more solid. The keyboard is ultra smooth, ultra quiet, and just makes typing a breeze. I wanted an illuminated keyboard because I tend to use it at night and don't like a lot of ambient light in the room. Even if the Microsoft keyboard were backlit (whch it was not) the text on the Function keys was far too small. This keyboard has larger, backlit text and is great. I keep the keyboard on the desk, the wireless aspect is mainly important to me for the mouse but it's still welcome for the keyboard. If I wanted a wireless keyboard for using on my lap I would think one with a mouse pad might be more tempting than removing my hand to grab a mouse on the desktop.It's not a cheap combo but you get what you pay for in this case. The fact that it just plain works out of the box with Linux is fantastic. Hopefully it will last!

A Logitech fan for decades, the company in my opinion has build it's strong reputation by remaining in the computer peripheral market and introducing innovative and progressive technologies.When it came to this model I had qualms about spending $150 for a keyboard and mouse. However after some thought and realizing both how much I have invested in my computers, why not give this a chance and see if the mouse and keyboard deliver on the promise and enhance the overall experience of working in front of my PC for hours at a clip.Right of the bat I'll tell you this is by far the nicest keyboard I've ever had and I've been using computers since the world ran on DOS Based 286 Antiques!Some nice touches regarding the keyboard are:* Wonderfully comfortable keys the "Perfect Stroke" technology really does allow for whisper quiet typing, the perfect resistance and more accurate and fast typing.* Great back lighting can be adjusted and senses your fingers immediately turning itself on and off after you're done typing.* Ultra slim, sleek design* Superb quality.As for the mouse, I love it, it's larger than the other Logitech mice we have which are all wireless as well and work on their three years of battery life from two double A batteries, a great innovation that I wish had been incorporated into this mouse. However the comfort level is a ten and the mouse is incredibly responsive.Some nice touches on the mouse include:* Ultimate comfort* extremely accurate performance and response times* Great Scrolling* Excellent variation of programmable buttonsI find the "Darkfield" laser technology to be a bit of a hype. So the mouse can work on glass, so what? All I can see this doing is scratching both your glass desk or table beneath the mouse and the underside of the mouse itself, not much of a selling feature.Although I've read some complaints about Logitech service my experience has always been excellent. When I called to register my MX800 and get some support for a year oldMK700 keyboard I was offered a replacement right away at no cost.What is more I like the Logitech unifying receiver, it's plug and play, can run multiple devices, takes up only one USB port and I find it more reliable than BlueTooth.On the somewhat downside, other Logitech combos at half the price carry a 5 year warrantee on keyboard and mouse. You get three years on the MX800. In addition the battery life is estimated at 10 days (less if you keep the backlighting on high) so you're still dependant on cables to charge both the mouse and keyboard.Less expensive models have as I mentioned earlier a 3 year run time without having to be charged. That technology should have been incorporated into the MX800 especially considering the price. However you can charge both via USB and still use both mouse and keyboard while you're charging up.Despite the few drawbacks, if you're looking for a superb keyboard and mouse that offer both excellent comfort and accuracy the MX800 is certain to provide a better work flow and efficient experience.Highly Recommended

I have been using Logitech's performance combo line for a while now. I had the Performance combo MX5500 before this but those were getting old and full of crumbs, grim, etc.First the Mouse:One of the main differences that I really like with the mouse is that you no longer have to use a charging cradled. The mouse uses a micro USB plug that works from any USB port to charge your mouse Also in the old Performance MX mouse it would automatically sense if you were trying to go into free scroll or not which could sometimes be problematic. In the new mouse you only have to press a button right under the scroll wheel to switch from click to free scroll. As with all performance MX mouses the forward and back buttons right above where your thumb hits are incredibly useful when web browsing or looking through folders.Keyboard:I am very impressed with the upgrades to this keyboard over the MX5500. First and foremost is you no longer have to use 4 AA batteries, instead you can just charge the keyboard directly with the same micro USB cable as the mouse. The backlit keys are a really nice touch even if not completely necessary. The biggest change from the MX5500 to this is that there is no longer a small screen top-center of the keyboard. Not a big deal as that was mostly a novelty anyways. Love the calculator button that quickly launches a calculator for you to do quick math.Software:Not much to say here its the same Logitech Setpoint software that they have been using for years. It works really well and gives you lots of customization options.Overall a very solid Mouse and Keyboard combo, I have been using Logitech for years and its obvious that they are still doing very good work. Highly recommended.
