5 out of 5 eggsGreat Keyboard

Pros: Light, no cables or batteries needed. I like the feel of the keyboard when typing. Is easy. Helps keep desk uncluttered, and I can put it wherever I want, and always works perfectly.
I first thought solar panel would be a gimmick, but it has been running strong for over three years.

Cons: No backlight

1 out of 5 eggsOnly good for 3 years

Pros: Works well in low light. Other than the MAJOR battery issue detailed below, I really liked the keyboard.

Cons: WARNING: It has a 6032 (thin coin sized RECHARGABLE battery) that is not only difficult to find but is NOT user replaceable. After 2 years, 6 months the battery has failed and I must send in the keyboard for replacement. Look in the Logitech forums for further confirmation. The keyboard is fine, just the battery failed. This is the only Logitech product I've had an issue with.

4 out of 5 eggsPerfect, but not for "cave dwellers"

Pros: I can easily say right off the bat that this keyboard is a logical step towards solving the one weakness all wireless keyboards had: a battery life. It also looks so stylish on the computer desk that isn't cluttered with wires. (Seriously, google some pictures. It looks modern and minimalist)
+ It is powered by the sun.
+ Very slim keyboard.
+ Very comfortable to type on. (For a rubber dome keyboard)
+ Looks very sleek.
+ Price is not insanely overkill for what it is worth.
+ Has a check charge button. (Which is expressed by a smiley and frownie face.)
+ Charges well. (When a direct light source is available)
+ Can charge while the keyboard is switched to off.

Cons: While it does solve the wireless keyboard problem, this keyboard isn't perfect yet. It actually requires direct light to charge it, not ambient. This is normally not a problem for those who use a computer with the lights off, but it is a problem for those who do. People generally will close the blinds to shade out the sun in order to see, this is enough to prevent a positive charge.

Another thing: when the keyboard loses some of it's charge (< 80%), it actually starts to lose it's connectivity a bit which causes some keystrokes to not register. I also noticed that the signal is not as strong as it should be. Having the receiver plugged in the back of the computer causes keystroke loss. So I had to plug it in more pain sight for it to fully work.

These two reasons were only enough to knock off one egg. The keyboard is amazing when it is put to use in the proper environment. But for the clique gamer or hardcore computer user, wired keyboards are the better way to go.
- Weak receiver compared to other wireless keyboards.
- Requires direct light for it to work.
- Needs a strong charge for it to be fully functional.
- No back light? (Not a con for me, but is for those who need to see the keys in the dark)
- Drop it once, acts funny forever.

Other Thoughts: A bright enough monitor is actually enough to help sustain a charge for a much longer period. A 23" 250cd/m2 brightness monitor gave it a charge enough for it to hold a >80% charge for 3 weeks straight. Imagine what a the modern 300-350cd/m2 monitors would do.

As for the last con listed above, my cat actually had jumped up to the desk. To his surprise, landed on the keyboard, freaked out, ran, and my keyboard landed on the floor. Now, the backslash button is highly over sensitive. Just laying my finger on there causes it to register repetitively. I understand it is because it was dropped, but it was a warning to others. Take good care of the keyboard and it'll last.

When the keyboard can type well with a weaker charge (like most other wireless keyboards) and has a more efficient power set-up, the keyboard will have to be considered the perfect wireless keyboard. (And maybe a back-light for those who need them)

5 out of 5 eggsNever worry about charging

Pros: Very thin, perfect weight, I never have to worry about battery life. This keyboard even works in low light settings.

Cons: The rubber feet may wear off.

Other Thoughts: I don't always write reviews, but when I do it is because of a great product. I highly recommend this keyboard for anyone that is always on the go and doesn't want to ever deal with batteries or charging.

3 out of 5 eggs

Pros: slim and sleek!

Cons: the number pad sometimes turns itself off. Also the keyboard sometimes just stops working and requires being shut off and turned back on. Minor inconvenience.

Other Thoughts: This is my second - Don't spill beer on it.

1 out of 5 eggs2nd keyboard in 1 week.

Pros: It is very nice looking. Solar power is neat if you want to look at it that way. It is very thin and light. A major plus to carry with my laptop when I need it.

Cons: The keys are sticking and "being clicked" when I just barely put my fingers on it. My first on was the R key. If I just gentle push upwards without pressing it down a bunch of rrrrrr's will appear. I brought it back to the store and got another one. 3 days later now it is happening with the Q. So while typing I will end up with things like, "rrrready, forrrrrr, qqquick."

Other Thoughts: I am returning it and just gonna opt for a larger normal keyboard. I do like Logitech stuff but this is the worst keyboard I have used in from them. My keyboard from 2002 at least types better. I give it 1 star as a keyboard that has problems using the main purpose it was made for fails at doing so.

4 out of 5 eggsGreat keyboard with a flaw

Pros: Comfortable
Good key resistance
Amazing battery life

Cons: A little flimsy
I have used two of these for the past 2 years and 2 months, and I will be receiving the third keyboard shortly through Logitech warranty. Reason for it:
1) On the first keyboard I had, the button corresponding with letter M got stuck.
2) On the second keyboard, buttons for "comma, period, semicolon and letter "L" either stuck or barely working.

Other Thoughts: Unlike some reviewers, I never had a problem with a battery life - the keyboard has never been exposed to a sun and throughout the day it stays in a shadow. During evenings, there is a 100W lamp glowing about 6 feet away from the keyboard and during nights I have all lights turned off. So far, the battery level has never gone below 90% for both of the keyboards I used.

4 out of 5 eggsAwesome keyboard, questionable indoor-charging

Pros: As many have said, this is a great keyboard overall.

You never need to plug it in (and you can't).

It has a sleek and modern feel to it, the buttons are quiet and low-profile. It's very solid feeling, heavy even, about twice as heavy as the logitech ex100 I was using before. Some might consider that a con but I like it.

There's a little sun-icon button that brings up a panel showing your battery%, as well as the Lux you're getting from whatever light is in the room, which I find to be a very unique and handy feature. How much more light are you getting in the living room vs. the bedroom vs. the porch? There ya go.

Mine arrived fully charged, that's always nice.

Cons: Battery - I think it has to be not-in-use AND in the light to charge well.

It's purported to be able to charge under sunlight or "even desk-lamp light," however, when I got the keyboard about a month ago it was at 100%, and now it's at about 81%. Certainly not bad, for a month of daily use. But then again, that means if I want it to increase or even break even, I have to change something, the light, how much time it's in the light, where I store the keyboard, and even though that might not seem like much, it does equal one more thing that you have to do, as opposed to just being able to toss the keyboard wherever and never worry about it.

To note however, probably 1/2 of my keyboard use is in the dark. I'm sure if you leave it alone and in the light for an extended time it will charge up, but if the room light's on, I'm in the room, and if I'm in the room, there's a good chance I'm... on the computer!

Line of sight - You do need to have a line of sight to the usb receiver. I initially had it plugged into my desktop pc, which is in the closet to help keep the heat, light and noise separated from my HDTV monitor and I, and with the door closed it would cut out frequently, from about 10 feet away. That's okay because I have a usb hub next to me anyway, so now it's there and it's flawless.

Other Thoughts: Super overall, I love not having to do anything, things like buy batteries, install them, plug things in, get my legs around a keyboard cord, things like that. This helps with those things, and my overall dream of doing nothing. Cheers! :)
