Summary: - I really wish they'd make more keyboards that didn't have the pointless numpad. I bought this keyboard because the ones without the numpad didn't have the features I wanted or were overpriced.
Pros: - Feels like it won't just fall apart or break within a year. - Stamped white lettering on the buttons are bold and very easy to see even in low light. - PC power button is great (also known as a sleep button depending on which settings you set your PC power management to). - Love the calculator ...
Cons: - I'd imagine the unifying feature would still be an issue if there's more than 1 computer using wireless Logitech peripherals. Haven't really experimented with that yet though.
Excerpt: I bought these for my office mates and am returning them. We type all day long and your fingers don't fit well and it's awkward. Odd experience for one that types by touch all day long. I have had great success with this brand but this model isn't the one for us.
Summary: Will buy again for my next wireless keyboard needs unless there's another keyboard that REALLY impresses me.
Pros: Battery life! It came with 2 AAA batteries 10/2012 and is STILL running on the same batteries 02/2015 in a daily use HTPC! According to OpenSUSE's tray battery monitor I'm still at 49% battery. Beat that!
Cons: Wouldn't prefer the profile of the keys for workstation use, but they do just fine on an HTPC.
Excerpt: I purchased the Logitech K270 keyboard in order to open up an additional USB port. I already had a Logitech TrackBall mouse, but had a Microsoft keyboard. I really love the track ball mouse!The keys were slightly larger with the Microsoft keyboard. I imagine I will get used to the smaller keys.
