      Avoid this keyboard / mouse combo, spend more


      So I had written a lengthy unbiased review, prior to accidentally hitting the "new to me" back button on the left side of the mouse and unfortunately the entire review is gone. Here is the short version. The keys are weak, lazy feeling. They do not move smoothly and make the keyboard feel very cheap. The keystroke seems long like a 1980's computer and a step back in time honestly. The keyboard layout gets a failure stamp in my opinion. Why any manufacturer would move the "Home / End / Delete / Page UP and Down" buttons is beyond me. Any professional who uses any of these keys will hate it immediately. Unless you like to hunt and peck with keys, you'll likely agree with me. The keyboard is wavy from left to right. This makes it nothing but awkward. Further, the W shape must be intended for folks with small hands as my lengthy fingers feel crowded more than ever on this large footprint keyboard so it makes me wonder if the arrangement wasn't shrunk down to fit all the bells and whistle buttons (do we really need a 1.5" square music or camera button folks? The top two inches of the keyboard are wasted space and the similarly sized space bar makes me wonder if anyone has EVER struggled to find the largest button on a keyboard since the start of time necessitating this one to be twice as tall.) In short, I hate this keyboard, and it's going back in the box to return as soon as this review is done. Onto the mouse. It's large size is what sucked me into this purchase. Spending $100 for the only other large mouse on display that fit my perhaps above average hand size was out of the question, why every mouse has to be designed to fit in the change pocket of your jeans is beyond me. Sure, a mouse for on the go should be compact but does everyone really operate on a desk the size of a notebook at home or are they small so keyboards can become larger to support surfboard sized space bars? The mouse wheel / center button lacks definition and accuracy. Not enough of a positive feel for my taste. Further, I can move the button a click at a time and see no change on the display regardless of the setting in the included Set point software. Speaking of which, it hung during it's initial "3 required updates" which is another bad sign that this thing was shoved out the door full of bad design. The buttons feel nice otherwise, granted make sure you want the back / forward buttons before they ruin your day too. However, big complaint #2 is the laser for this mouse tracks very poorly. I've tested it on a wooden desktop, used a mouse pad, tried it on a sheet of paper, etc. Spotty at best even after properly configured. Reminds me of an old roller ball mouse with lint stuck in it. Speaking of lint, the underside where the laser is recessed is a terrible design. It has a cylindrical hole smaller than a pencil eraser on the underside about 1/3-1/2" deep just begging to be clogged with lint or dirt and requires you to hunt down tweezers and a q-tip to fish out. Another Logitech mouse I purchased over a year ago has a angled opening making it possible to fish anything out of / clean with a simple tissue so this is a step backwards in design in my opinion. So, I would pass on this model despite it's attractive price tag. The fast buttons are a nice feature, but I'd prefer they be programmable. Perhaps this keyboard has a niche though, older folks with arthritis may find it comfortable and enjoy the large "simple" buttons for one touch access, but if you're a professional like myself who was looking for a keyboard to spend 40 hours a week behind keep searching and do what I plan to do, spend a little more and remember you get what you pay for!

      Good product, decent price point

      • Verified PurchaserVerified Purchase

      For wireless keyboard/mouse combination, I think this is a pretty good buy. Over the years (I've been a programmer since 1964) I’ve been through a fair number of keyboards. These days they are all generally made the same: a thin sheet of plastic with conductive ink printed on it, covered with a second “spacer” layer of plastic with holes in it, and finally a third piece of plastic with conductive ink. The keys press the top sheet of plastic down to make contact with the bottom sheet. In time, the conductive print can wear, especially on frequently used keys like E, S, T, etc. You start having typing problems. As a retired engineer, I have more than once turned the keyboard upside down, taken all of the screws out, opened it up, cleaned the conductive ink, and put the whole thing back together again. When this fixes the problem, it usually doesn’t last very long. So, keyboards don’t last forever and have to be replaced. I happen to think this particular keyboard/mouse combination from Logitech is a pretty decent product for the price. It sets up easily and has an inconspicuous USB wireless receiver which you can plug into your system just about anywhere and it does not get in the way. Remember though, if you’re a gamer and want a smart and illuminated keyboard, you pretty much have to buy a wired USB keyboard as that’s where the power comes from. I have a couple of those too.

      Excellent Features & Functions


      The list of available functions are intuitive and laid out very well. Not accustomed to using a curved keyboard of late, the shift, Windows and control keys required several days to become familiar with, as upon initial use, I was typing the wrong keys when attempting to perform short cuts, but now that I am familiar with the placement of those keys, workflow is much quicker and more natural. The keys are relatively quite. For a fast typer and one who works with live audio and video, this was one of many welcomed attributes. The soft palm pad provides comfort and just enough grip to keep your palms in place. A few of the function keys could have been made to have their own button, but then again, it is rare that I use them. The overall keyboard could be slimmer, even with the audio and other buttons remaining in place. There is a lot of wasted space at the top of the keyboard, where the audio controls are located. Elminating this wasted space, would slim the keyboard down just enough to allow the keyboard to fit within my soft Ogio brief case. Battery life is impressive on the keyboard and mouse. I kept them on nearly every day throughout the month I have owned it and have yet to burn through the batteries. The option to turn each of separately is great when one of them is not in use. The mouse is precise and equally ergonomic. The overall feel is amid the best I have owned. For the features and functionality, I would be willing to spend much more than I spent on this package, but it was considerably cheaper than others in its class. Thanks.

      A Good value

      • Verified PurchaserVerified Purchase

      I have had this keyboard/mouse combo for about a month now and it has been fairly good so far. I am using them with a Samsung all-in-one running windows 8.1. The first thing you will probably notice is the size of the keyboard. It is certainly larger than the notebook sized one that came with the computer, but also larger than any other standard keyboard I have used in the past. This is not a big deal to me, but if space is limited for you, it may be something to take into consideration. Installation is about as straightforward as it gets, just plug and play. Windows found the drivers and installed them automatically. This allows the keyboard to function, but some of the features will not work without the installation of Setpoint from Logitech website. Unfortunately for me, I have been unable to get Setpoint to work correctly, so I am still unable to use of some of the keyboard features, such as the applications switcher. I am not sure if I would use this or other features, but I will never know if they are not options. That being said, the volume and video playback controls work rather well and I find myself using them quite often. The keyboard itself is pretty comfortable and doesn’t strain my wrists like others in the past. The keys are a bit noisy and at moments there is some lag time, but that actually appears to be getting a bit better the more I use it. The included mouse is actually very nice and I am extremely happy with it. It is accurate and easy to maneuver. The forward/back browser buttons are also extremely convenient once you get used to using them. There are a few issues with the software, and hopefully I can get them figured out, but all in all the ergonomics are a pretty big step up compared to other keyboards/mouse I have used in the past.

      Mouse connection issues


      When I got my product home, I plugged it in right away and the software was installed automatically and within seconds it was ready to use. However, also right away I was having problems with the mouse being 'jumpy' or 'laggy'. So after this happened I tried plugging the USB from the back of my computer to the front, didn't help; I tried taking away my mousepad and using it on my flat desk, didn't help; so I ended up just switching back to my wired mouse. On the plus side, the keyboard is comfy and very quiet. So for the keyboard, I would give it 4-5 stars, but the mouse, probably 1-2 as it makes it very difficult to do anything. So overall: Pros: - Keyboard is comfortable - Many defined and customizable buttons such as: application switcher, zoom button, pictures, music, media center, calculator, and power button; additional functions that you must hold the function (Fn) button down to use. - All buttons are completely customizable and can be turned off if you wish. Also, caps lock, windows button, num lock, and insert buttons can be disabled. - Mouse is also comfortable - Mouse also has customizable side buttons - All wireless - Fairly good price Cons: - Jumpy mouse (most likely connection issues); unusable in my case - Wave design may not be for everybody So overall, I have no problems with the keyboard but because of the problems with the mouse, it kind-of ruined it for me. I'm a little disappointed, usually Logitech is reliable.

      Great overall comfort; had issues with connection

      • My Best Buy® MemberMember

      I recently bought this product thinking I could kill 2 birds with one stone. Mission accomplished, for the most part. After installation, I ran into some issues in which the keyboard and mouse would lose connection to the receiver. After checking my driver and reading the troubleshooting from Logitech, I came to the conclusion the interference was due to my wireless network antenna. Logitech recommends keeping the receiver 8" away from other electronics; a difficult feat for some PC layouts. I ended up using the USB extender (which is included) to route the receiver up to my desk space right in front of the keyboard and mouse. After making that adjustment, I haven't had any lag or connection issues; however, I don't exactly feel like I have a wireless setup since I now have to remain so close to the receiver. The fix I described works for me since I'm on a desktop and don't expect to be moving around too much, but this products' interference issues would be a disaster for a laptop where the wireless card/antenna is very close to the USB ports. Hopefully, they can find a fix for the interference issues since just about everything in the house is going wireless. In summary, a great looking/feeling/easy to operate combo as long as wireless network cards/antennas aren't nearby (<8").

      Great product, Having trouble...? READ BELOW...


      Great product, got on sale so great price. If you are having any second thoughts because of some of the reviews, or are having trouble with this device please read below... Check to see if you are running other electronics in your house that use 2.4GHz. That might explain any problems listed by those that give this a low rating. I have the keyboard and mouse and love it, however I threw out a 2.4GHz phone that I really don't use anymore anyway because it was causing interferrence. (Make sure you have DECT 6.0) I also have a wireless security camera that works on the same frequency, along with a baby moniter. These devices didn't interfere with each other that much, (I did have some problems with the camera, however I was able to tweak the settings to use 2.32GHz) The fact that the others didn't cause too many problems before and the keyboard and mouse do is because they don't have a scanning device like the phone to jump between small fluxuations in the frequencies to adjust to any interferrence. If those listed above don't fix your problem then you got a lemon and should take back and get a new one. That doesn't make it a bad product overall, I have yet to find any product from any company that doesn't have any units that are sold without having a few problems. It is a great product as long as it is comfortable for you, as some people don't like the physical setup, or the size of the mouse.

      OK for amateurs with Windows


      I hooked it up to windows and got the setpoint software after a lengthy setup process to program the hot keys I got almost everything but media center working properly. The real problem was when I hooked it up to my Mac. I downloaded the required zip drive of logitech control center for the mac and it would not recognize the keyboard. Since I bougt the wireless wave "Combo" I assumed both would work. I can type with the keyboard but as far as being able to one touch open itunes or anything else for that matter, for get it. I ended up calling support twice waiting over 30 minutes only to find out none of the new keyboards in 2010 or newer will work with a mac(typing will but programming hot keys wont). Since I use my mac more than my pc this product and for that matter the whole product line up of new keyboards from logitech fail my test. I will return it and get an older keyboard from logitech or a newer keyboard from apple. BTW the way the keys go up and down on this keyboard took me no time at all to learn, although I'm not sure that its a benefit, its just different. A huge pro for this combo is the mouse, being able to scroll horizontally and vertically with the m510 which is the mouse part of this combo is very convenient and the thumb button that lets me go back a page or forward a page when web browsing is super helpful. I will buy the mouse separately, I think it's even better than the magic mouse from apple.
