Summary: I'm typing on it right now, and although most of the keys work okay and have decent feedback, there are a few rebellious keys. They aren't consistent in required pressure. For example, the backspace key takes more force to push down than the other keys and doesn't spring up as quickly. I think eventually this keyboard may break in, but so far (a few weeks), I am moving back to a new (old stock) Lenovo keyboard.
Summary: Good product and next day delivery ("Standard Delivery" option). I have a UK version of this keyboard that is 4 years old and the lettering on the keys is as good as new which was the reason for buying this product for a friend who lives in the U.S. As the previous reviewer mentioned, this is the Standard US keyboard layout and does NOT include the "Alt Gr" key (with the associated special characters)that feature on the US International keyboard layout.
Summary: Keyboard they showed as the image showed the US International layout version, however the US standard version is what I was shipped. Pretty disappointed about that. Keyboard is alright for a rubber dome keyboard. A bit flimsy when applying moderate down-force; a bit of give in the middle of the board.
Summary: Cherry quality. Nice consistent feel to keys. Totally standard layout. Terrific for extended keyboard hammering and serious work. USB plug and 1.8m long lead. Better than a Miscrosoft wired one for similar price. Highly recommended.
