      Great Wireless Set for General Use

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I purchased this set for general use, such as word processing, movie editing, online browsing, etc. and it performed up to expectations. I usually have problems with flat keyboards (non-raised/spaced keys), and I noticed some reviews complaining about that issue with this keyboard. It's not like a traditional keyboard, but the keys are spaced enough and raised enough to fall somewhere in between a traditional and a flat keyboard. I have no problems with this key design, Both the mouse and keyboard are responsive. In using the mouse for movie editing, the response on the mouse was both smooth and fine enough that I could do small details without any issues. The mouse functions perfectly on most surfaces, although, I haven't tried a glass tabletop. Setup was as quick and painless as I could expect. I am using this set with Win 7, and it's as easy as just inserting the dongle and going - no setup, no additional software in the background, etc. As far as battery life goes, I haven't been using the set long enough to determine. For online gaming, I would recommend looking at different models. This is because the only issue I have had with this product, and the only reason I went down to 4 stars was after an undetermined amount of time, the mouse drops connection with the dongle. Turning the mouse on and off does not fix it either. You must remove and reinsert the dongle to fix the issue or remove and re-insert the battery. Now this has happened so infrequently and so rarely to date, it is a non-issue for general use; however, it is not something you want while gaming. To preempt additional questions, I replaced the battery after the first time and it happened a second time withing a relatively short time frame - checked the battery after the second time and it was full. I might have a defective mouse (or an issue with the internal battery contacts) and it might not be representative of the model, but since I am not using it to game and I have only had 2 instances after hundreds of hours of use, I am fine with it. So overall, for the price, I would say it is a 4/5 star product, if the mouse issue is not representative of the product and a 1-off issue, I would say 5/5.

      Items work, but have major problems


      I bought this keyboard/mouse combo in November, 2011. I chose it over the other options for several reasons. 1.) Quiet keys. I hate excessively loud keyboards. 2.) Wireless convenience. Short version of why I would not recommend this product: For me, the ability to clean a keyboard is 100% necessary and not being able to is an absolute deal breaker. I would not have bought this keyboard if I had known. I had no idea anyone even made keyboards with non-removable keys, since that defies common sense. Keyboards get dirty. Details: Minor problem: 1.) Wireless range is very bad. My mouse 1.5 feet from the front of my computer, where I now have the wireless receiver plugged into a USB port and it works fine. But before that, I had the receiver plugged into the back, so perhaps 3.5 feet from the mouse, and the signal was too weak. The mouse would not always react to my clicks, etc. Major problems: 1.) Mouse middle-click has begun to fail after only 6 months of use. I now have to press down hard on the scroll wheel for the middle click to register. This is not a wireless issue, as I have just replaced the mouse battery. There is no problem with scrolling or the other mouse buttons. 2.) Impossible to clean keyboard. I spilled a drink on the keyboard (it happens to everyone, doesn't it?) and now my "2" key on the numpad is completely stuck. Most keyboards have easily detachable keys so that you can clean them. This one does not. I put a fair amount of upward pressure on the key and it did not come off. In desperation, I even poured water into the numpad area of the keyboard several times and the key did not get unstuck. So far, there is no other reason for me to want to remove keys, but after a few years a LOT of stuff will accumulate between these keys, as they are well-spaced, and there will be no way to clean it out. Deal breaker. . Positives: 1.) Battery life was pretty good: about 5 months of daily use several hours per day, although I consistently turn off the keyboard and mouse at night. 2.) Off switches. I like turning off the keyboard and mouse to increase battery life and also to confuse unauthorized would-be users of my computer.

      More Than I Thought I'd Get

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I am a fan of Logitech and typically buy their keyboards and mice or Microsoft's. I didn't expect too much from this little combo because it's cheap (price wise) and it's a basic keyboard and mouse combo. However, I was pleasantly surprised by what I actually got from it. The mouse is one of the solid, heavier weighted mice that I like because it doesn't float around under you hand. You can feel it and the weight makes it easier for me to move in finer increments. Solid construction makes it feel like you can use it without being afraid of breaking or damaging it. The keyboard is a straight forward flat keyboard with a few multimedia buttons and some function keys. Nothing big or fancy, but it is smooth to type on and keeps up with you as you type (any decent wireless should be able to do that, but I've run into some even recently that cannot). The keyboard nor mouse requires a lot of wake up time. When you don't use them for awhile, they reconnect and are active almost immediately. This is a very welcome feature. My biggest complaint is the same for all the Logitech combos. They require a separate dongle to use instead of using Bluetooth. The dongle is small and pairing is super easy, but it's still an external dongle even if they are universal for Logitech. I wish they had the option of going Bluetooth or dongle, on the same keyboard. I've had Bluetooth keyboards and mice in the past that lost pairing, took awhile to wake up, and disconnected and wouldn't reconnect until a power cycle, but when i travel I'd still like the option of not having to keep that separate dongle.

      Use is for my Samsung Smart TV

      • My Best Buy® MemberMember

      I bought this wireless keyboard with mouse to use with my Samsung 55" Smart TV. Typing and pointing with the TV remote is tedious and time consuming. Samsung recommended their wireless keyboard for about $100.00 but there were people who said you could use Logitech's K400 wireless keyboard and it worked even better than the Samsung wireless keyboard. The problem with the Samsung keyboard according to reviewers was that it wouldn't work very well with Netflix and other sites and was pricey. I decided to try this Logitech wireless keyboard because it came with a mouse and was the same price as the K400 at Bestbuy - $39.00. The K400 keyboard has a touchpad and I prefer to use a mouse over a touchpad. The MK520 was pretty much plug and play. I was hoping that the keyboard and mouse would work with all the internet sites that I use but I was somewhat disappointed with the results. For example, like the other keyboards, it doesn't work with Netflix. Also, I could not type in my user name and password at the hotmail website. The scroll wheel works for some sites but not others. Ideally, what i wanted to do was surf the internet on my smart tv as easily as I could with my laptop or my desktop computers. This has not been the case. Pages load more slowly on my smart tv and the wireless keyboard and mouse work adequately. This is not the fault of the keyboard. In conclusion, for light internet surfing, this keyboard and mouse is fine with my smart tv. For fast and heavy surfing, I would use my laptop and desktop. Hope Apple TV is better than Samsung Smart TV.

      Not for people who need to be productive

      • My Best Buy Premier Silver MemberElite Plus Member

      I wanted a Logitech because that's all that I've ever owned. My last keyboard combo from them lasted 4 years and with daily abuse, finally kicked the bucket. I demo'd this board in-store, but bought it hoping that the angle on the keys would be better while sitting. Well, it wasn't. Left hand Alt key is awkward due to the fact that the buttons sit flush with the trim of the board. In order to press the left Alt, your thumb needs to go deeper than the trim, which isn't a soft edge. Similarly, the lower arrow and CTRL keys are awkward to press due to the same issue. I probably wouldn't mind as much if this were for my home PC, but I absolutely cannot be productive and comfortable with this at work. The mouse had issues on a soft pad where it would not track straight. The pointer would literally jump up and down as you dragged it across the screen. My other 2 logitech mice do not have the same issue. In order to correct, I needed to remove the pad, which just isn't as comfortable. Also, the feet on the mouse are just standard plastic, and does not glide well at all. Very disappointed in this one, as I have been a faithful to this brand for years. Am returning to the store for different model.

      very good, and good value when on sale


      was looking for a wireless keyboard for a new home theater pc (htpc) I built. I already have several logitech products; all good. I saw this combo; did not really need another basic wireless mouse (had one) but thought that I would get the combo based upon the reviews of the keyboard - very glad that I did. keyboard is full size, nice feel to the keys. a little different than a 'standard' keyboard, but not different in a bad way. Thin and light weight in a good way. overall, a nice keyboard (in general, as a keyboard) and double nice in that it is wireless. separate media buttons are nice for volume and playback. mouse is surprisingly good - nice feel in the hand and very precise accuracy. but, I wish it had the browser page forward, page back buttons. will have to get one with that feature myself some day, but for now this mouse is good enough for the htpc and basic use. plug and play operation. absolutely no connection issues, or keyboard or mouse lag, from about 15 feet away. got it at BB on sale at 1/2 price.

      My Favorite Keyboard

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I recently hung my monitors on a dual monitor arm and hid the cables so the only wiring on my desk was a mouse and a keyboard. This was unacceptable. A few of my co-workers have this same Logitech keyboard and mouse so I did some searching around and found Best Buy had it for less than I could order it online when you factored in the shipping charges. I ran over on my lunch break and picked this up. The keyboard works great, the keys are quieter than the old Dell USB keyboard I replaced. The mouse feels comfortable also but I do wish it had the forward and backward thumb buttons which are handy when using the internet. One co-worker says he has left his powered on for over a year and the batteries are still the originals. I turn mine to off every day when I leave work and I hope for as long of battery life. The manufacturer says 3 years which is a long time. I will be buying another one of these sets for my home PC as well.

      Exactly what I need, and Linux compatible too


      I bought a Microsoft 800 wireless desktop set and it worked great, but I needed something with a bigger Escape key. This was the one. It is just the right size , the key layout is comfortable and the caps lock key has a light, something still a little rare on wireless keyboards. The sound up/down keys work with Linux also (Ubuntu 10), as does the Print Screen. It is just under 7.5 inches deep so just fits in my Fellows keyboard tray, and it is low profile, allowing me to slide the keyboard tray under the desk when not using it. This was also true for the Microsoft 800. Both are fine products. This one is larger and more expensive, so it is just a matter of preference. I gave the MS 800 to my wife and she is very happy with it. I found some old web flames about Logitech not being compatible with Linux, but this is no longer so, at least for this product. At $60 it is a little pricey, but it is the cheapest one I could find that would fit the tray, and had the features I wanted.
