Keyboard is fine, but the center tracking wheel is clunky - you can hear the cogs of the wheel go round and round - lol.

So I finally went for a wireless keyboard/mouse set up. I was looking at getting a new macbook, and I wanted something that i could use both with my desktop (a ubuntu box) and the laptop. normally, i would consider a wireless keyboard to be overkill for a desktop (how much do you really move your keyboard around?), but for a laptop, it makes sense. Anyway, I decided to go for this setup.

The mouse is nice. I like the side buttons and tracking is smooth. The horizontal scroll wheel is kind of annoying, but most mice come with this these days, so it's not really  a fault of this particular mouse.

The keyboard, though, is sort of lame. I hate the key action, it's way too loose. The keys kind of wobble when you hit them, which sometimes makes me second-guess a keypress. I much prefer a keyboard with stiffer keys and a springy feel. This keyboard is kind of flaccid. I wish I had taken the time to look at this one in a store before buying it online, but impulse buying has got me again. Oh well, it's not unusable, just not ideal. Guess I will learn to live with it.

Key travel on this sort of sucks so when attempting to type it really is annoying.  I love the size and the trackpad and for a simple media keyboard it works fine, but don't expect to type anything long on it without constant mistakes.

The keyboard is great, wonderful action, I enjoy all of the shortcut buttons and it is very comfortable. The mouse on the other hand is very spotty, it jumps around the screen a lot and wastes time...

The mouse seems to work fine, but the keyboard has serious lag - although it is less than a foot from the receiver.  I finally went back to a corded keyboard.

The mouse wheel has some scrolling issues... other than that; love the keyboard and the keyboard alone is worth $30 in my opinion

It's nice that it's solar so the batteries never need to be replaced, and it's one of the few Logitech keyboards that still maintains a standard 109-key layout (keeping the insert, delete, home, end, page up, and page down keys in their normal places while also having a full number pad), but it has some major drawbacks still.
The keys themselves are chiclet style, but unfortunately not as nice as a good laptop keyboard.  Comparing to one of my slightly older full keyboards, it's obvious the entire keyboard footprint isn't a 100% layout, so all the keys are slightly smaller than standard.  It's not hugely significant, I'd guess about a 90-95% layout size, but it makes a big difference if you're a very fast typist who uses a wide range of keys (like a programmer).  The keys themselves aren't actually that nice, despite the literature from Logitech.  The chiclets click more than most, have a pretty stiff spring to them, have a longer throw than any chiclet keyboard I've seen before, and when they do bottom out (I type like I'm on an old-school long throw keyboard) they hit hard instead of having a softer padding. The keys are slightly cupped however, just enough that your fingers will tend to drift into the middle of the keys instead of slowly drifting off the edges.  For comparison I used an illuminated model from Logitech and found the keys to be of significantly nicer quality and comfort.
My biggest complaint about the keyboard though is an absolute deal breaker for me.  As a programmer I use extensive sets of strange key combinations (Alt, Shift, Ctrl, Win) and I discovered that the Win+Shift key doesn't seem to work on this keyboard (even when using the latest firmware).  This is a problem I've seen on other keyboards, even some older Logitech keyboards, where they clearly don't expect certain keys to be used together, and whether its a problem with my specific device, or a problem with the entire model, it's causing me to exchange the device for a different model.
In summary, if you're a programmer or need to do any key combinations using the Win key, I'd give this keyboard a pass.  If you've been using a full keyboard up to this point, I'd also encourage you to give it a pass, but only if you do significant touch typing during your day.  Unless you need the solar feature (how often are you really replacing the batteries on your keyboard really?), I'd go for the wireless illuminated keyboard also made by Logitech instead (unless the illumination is a deal breaker).

The keyboard is ok. I don't like how flat everything is and I end up mistyping more frequent especially the 10-key. The mouse that came with it feels really cheap so I am using my Logitech M310 which feels so much better.

The connectivity isn't the best.  I love typing on the keyboard but I'm not thrilled with the mouse.

8/4 - The Shift Key started making a clicking sound.  I thought I would just live with it until I noticed that it was clicking even while I held it down and typing another key.  That's when I thought the issue might not just be the key hitting the base or rubbing up against another key.

As much as I've enjoyed typing on the soft keys, I'm returning the product.  I've ordered another Logitech keyboard with the same 'Soft Touch' keys.  Hopefully, I won't encounter the same issue.

BTW, there's a small gap between the clear edging and the main body of the keyboard that was starting to collect dust/dirt just after a month of use.  It may not bother some but I'm sort of a clean freak so it bothered me.  Pity... I did like the look of the clear edging...

Kind of starting to lose my faith in Logitech.  I ordered a lesser model a while back and ended up ditching it because it wasn't fast enough to register triple clicks and I had to remove the battery several times a week to make it register with my computer.  So I upgraded and bought this one ('cause I'm a long time fan of Logitech) but I find that I can't use the middle button effectively.  The scroll wheel is overly sensitive and doesn't "lock in" to the notches the way it should.  Just brushing it will make my page scroll one space.  So when I try to middle click to open links in a new tab I often end up scrolling the page one jump and missing the link instead.  Now a few weeks into owning it the middle button keeps registering a "left tilt" when I try to middle click.  I'm right handed and use my index finger to click so if ANYTHING it should be mis-registering a "right tilt" on the scroll button.  Instead, when I try to middle click a link I end up going back instead...and then I can't go forward because the right tilt on the scroll wheel doesn't work at all.  I'm going to have to look into another brand.  Logitech has officially lost my business.

The keyboard is great.  It feels solid and has most of the features anyone would want.  I love it!

But the mouse is the worst thing I've ever used!  The main problem is that the scroll wheel is intermittent.  But the resolution is also poor.  It doesn't seem to be a product that you would expect in the 21st century.

However, I took another reviewer's advice and removed the batteries from the mouse after the computer had booted, and reinstalled them.  The scroll wheel now works much better. It's still not great, but it's more or less usable.  Many thanks goes to the reviewer who provided this suggestion!

Bought this just over a year ago and the scroll wheel and left click have issues. The clicks/scrolls don't register about 25% of the time which is obviously an issue for gaming. The keyboard has worked fine and I don't have any complaints. This combo is fine if you're starting out on a budget, but there is a reason it's only $20.00.

It's okay, but just okay
1. You can throw the mouse away right away. The way the scrolling wheel feels and sounds is intolerable, the cursor moves way too quickly. The scrolling wheel alone turns the mouse into junk.
2. The keyboard is okay (I bought this set for the keyboard). The designers tried to make it more esthetically attractive, but forgot to make sure the multimedia buttons don't feel too loose and the part above the battery section doesn't feel loose.
It's usable and good enough, but this world & Logitech are obviously loosing the reasonable perfectionism.

Keyboard works fine, but I am not a fan of the key configuration in the lower left.  The CTRL and ALT keys are in a different order than typical keyboards.  For people who utilize them a lot to switch from screens or tabs it is frustrating.  If you don't typically utilize these keys for navigating then I would recommend this.

I've used this for my primary and gaming mouse for a very long time now.  I bought when it was first available at the MS store.

The middle button (scroll wheel) is very hard to click reliably.  It is just too stiff.  The wheel function itself is great though.

The thumb buttons are okay though they could stand to be a little less stiff as well.  Not as much of an issue because it is my thumb, but still...

The mouse is fairly accurate on a plain desk.

I think I'm about to swap it out for a Razer Deathadder 3500 though.  I just played with one at my friend's house and it felt better in every way.  I might also try lowering the weight of this for a while and see if that helps, though it won't help stiff buttons...

I only use the more accurate, less "fast" mode sometimes in FPSs, and then I tend to turn it on and leave it on.  Middle setting is perfect for everything else on my 19??x1200 monitor.  So ultimately the switchable nature of the mouse is kind of pointless for me.
