Summary: Unlike what has been said before, the battery IS replaceable. Though the battery is indeed hard to find (and it needs to be the exact same type, to boot), the battery tray can be opened with commonly available tools, such as a flathead screwdriver. You do NOT need to take the whole thing apart to change the battery. The battery is in a tiny tray underneath the surface, in between the Logitech logo and the left solar panel.
Pros: - Very slim and light compared to most other keyboards (i.e., very, very portable for a non-rollup keyboard) - Very long times between battery replacements - Keys aren't too heavy, but aren't really light, either - Charges rather quickly, even in low-light conditions - A quick press of the charge button indicates whether the environment is providing a sustainable charge (green for charging, red for discharging) - Discharge light blinks red when the battery gets low, s...
Cons: - The black finish on this keyboard means that any sort of dust or hair that happens to land on it is going to show up - Scratches that occur are fairly noticeable
Summary: Very nice looking product and high quality material. Work perfect. I don't know if this keyboard is good for a person who type a lot. I believe the range of the wireless is short because in a couple of time when a type I don't see what I'm typing immediately but 3 seconds after. I have it connected to a very short rage.
Excerpt: Had my first 750 for a year when it stopped working. Tried everything, but had to buy a new one. Logitech did finally get back to me with customer service, but had already spent the $ on a new one by then. I am still waiting for a return authorization to send back to defective keyboard. Otherwise, love the action and feel of this keyboard. It's the only one that works with my Contour scrollbar mouse, which needs a minimal space between bottom keys and edge of keyboard.
Excerpt: This is a real find: Slim profile, great keystroke action, recharges as advertised, from any light source. I've only had one problem with it, and that might be a compatibility one: Can't get the volume keys to work. Previous keyboards (wired type and wireless) worked fine, so be advised if you have that problem. There are a couple of other features I have not used, but generally don't use as a rule, so it's not known if they might be problematic, but I doubt they will.
Excerpt: The wife is very happy, no more changing batteries! She uses it for work up to 12 hours a day and the sunlight takes care of it all day long. She is very happy with the feel, I on the other hand am more happy with my much older HP that feels more like an electric typewriter. Much better than a mac keyboard that is way to flat feeling for us if that helps.
Excerpt: For our conference room we wanted a wireless keyboard that liberated the person typing from the corner of the room. A keyboard that could be used right on the conference table facing our large projection screen. Since we have important customers visit often, it had to look neat and professional. For me, I also didn't want to have to replace batteries on it every week, so the solar part of it is an extra perk.
