Logitech MK750 Wireless Solar Keyboard & Marathon Mouse Combo

A few years ago on a whim, I picked up the Logictech Marathon mouse, because my work mouse had a very loose mouse wheel. At the time, it was a bit of a hard decision, as it was a $40 mouse, for work. But it was wireless and batteries lasted 3 years, so, why not? I ended up loving the mouse. A year later, I started having similar issues with my work keyboard, and decided to get a new keyboard, and ended up deciding on the K750 solar keyboard. I was concerned about lighting issues, but that ended up not being an issue for my office space.So, this combo then? Given that I loved the mouse and keyboard so much, and had so little issues with either, I decided to get this, which ended up being slightly cheaper than I could find individually. Here's been my experience these items so far.Mouse: the 3 year battery life is probably overstated, though I'm not sure how they came up with that number. My original mouse lasted about 18 months or so with the batteries that were included in the package. I haven't had any issues with the mouse, though I have noticed that the new mouse wheel is a loose, so when moving the mouse forward and backward a lot, I sometimes inadvertently scroll up or down on whatever I'm working on. The lock button solves that issue, but I don't love turning the lock on and off all the time.Keyboard: They keyboard works pretty well. It's a fairly standard chic-let style keyboard, though does have some laptop style function buttons. It feels similar to a laptop keyboard, with an overall short stroke distance.That said, I do find it slightly more comfortable than actual laptops. The keyboard is nice and quiet to use, which I think my office mates appreciate. The only problem I faced with this keyboard was when the backspace key cap broke. This happened a little over a year after I bought the keyboard. I contacted logitech, asking for a new key (since I was still under warranty), and rather than sending me a keycap, they ended up sending me an entirely new keyboard. I got to keep the broken keyboard, which worked great, as I was able to buy a new key cap from ebay for about $3. I haven't had any issues with battery life. My office space was next to a tinted window, where we would primarily keep the lights off. Now, i sit in a cubicle with only florescent lighting, and both areas worked fine. The new keyboard sits in a much darker corner and seems to charge enough during the day to keep powered at night. Note: there aren't any LEDs for the capslock, numlock and scroll lock buttons, so it can difficult to determine if those are on.Overall: I would definitely recommend this combo. I'd only be concerned if I worked in very dark area, due to the keyboard. Performance wise, I think this works great as an office space keyboard and mouse. Once at home, I have played several games with this keyboard and mouse and would recommend it, but I know the community can be quite picky, so if you're super concerned about response times, you may want to look at other mouses and keyboards. I would say that there aren't any issues with more relaxed games, or with less competitive-oriented players.

I chose to buy this combo to replace my old Logitech solar keyboard which, at a couple of years old, had developed problems. First of all, its recharge capacity became severely limited over time to the point where it was almost impossible to charge it in natural light and it was forever giving me low charge warnings. Secondly, a couple of keys on the numerical keypad had become "sticky," i.e. they took a while to pop back up after pressing them (very annoying as you can imagine).I also wanted to replace my Logitech MX Anywhere mouse, which although I loved very much, had developed a problem wherein the left mouse button was frequently registering two clicks when I pressed it once (again, very annoying). I noticed that this combo deal included a different mouse, the Marathon, which looked to me to be virtually the same except a little bigger and with a much longer battery life.Well, this purchase didn't go too well for me. First of all, the keyboard was shipped with a dime sized patch of moisture under the plastic covering on one of the solar panels. I could move it around by pressing on it. I thought it might go away in time, but after nearly a week it became clear it was there to stay. The item was securely wrapped when I got it so I can only presume the moisture got in there at the factory. That's some bad quality control - it should never have left the premises!Onto the mouse. I had two problems with this - firstly, quality control. The clickable mouse wheel would sometimes, again, register two clicks when I pressed it. This was inexcusable. Secondly, the design of this mouse compared to the MX Anywhere is terrible. On the MX Anywhere, there is a middle mouse button directly under the wheel which by default is set to open a link in a new tab in your browser. This is so convenient! The Marathon Mouse also has a middle button, but it's to toggle the mouse wheel between smooth and notched movement. What's more, it doesn't work very well (I found myself pressing it three or four times to register the change). So how do you open a browser link in a new tab with the Marathon? Well, you do it by clicking the mouse wheel. This sounds OK in theory, but in practice it's as annoying as hell. It's almost impossible to click the mouse wheel without actually moving the wheel itself, so I frequently found myself scrolling the screen before the click was registered - which means you miss the link. I cannot describe how infuriating this is compared to the middle mouse button on the MX Anywhere.So the upshot is that I returned this package for a refund. I decided instead to purchase the keyboard (which I still wanted) in a retail store, and to purchase another MX Anywhere mouse separately. It cost about $25 more doing it like this, but I figured it was worth it.HOWEVER. The new keyboard, while being completely free of moisture patches, also has a problem. The left CTRL key isn't set right and it sometimes sticks when I press it. I have concluded that the standard of manufacturing at Logitech just ain't that hot. Oh well...maybe it will unstick in time. At this point I cannot be bothered to return yet another item.
