  • The image shows a close-up of a black keyboard with white lettering. The keyboard has a variety of keys, including the numbers 1 through 9, the letters A through Z, and other function keys. The keys are arranged in two rows, with the top row containing the letters and the bottom row containing the numbers. The keyboard also has a space bar and a shift key, which can be used to access additional functions. The keyboard is likely designed for use with a computer, and it is likely that the keys are labeled with their corresponding functions to assist users in typing and navigating within the computer system.

  • The text on the image is a jumbled mess, but it appears to be a description of a man using a computer. Here is a corrected version of the text: "A man is sitting at a desk, working on a computer. He is wearing glasses and typing on a keyboard. The computer screen is in front of him, and there is a cup nearby. The man is focused on his work, and the scene suggests a productive work environment."

    I replaced my work station Dell keyboard with this Logitech mechanical keyboard. I am on the keyboard all day and like the feel of a good old mechanical. They remind me for the keyboard that came with a computer's back when they first came out. Good solid construction and great key action. This feels like it can take a beating and still work. Took me a day to adjust to the new/old feel but happy with my purchase. One thing I wish it had is a on/off light for numbers lock but no big deal.

    Great looking and comfortable keyboard. Only mechanical keyboard I’ve seen that doesn’t have an over the top gaming keyboard look. Would love if it had dedicated macro keys but of course it’s not geared towards gamers. Some may miss backlighting but I am fine without it. Features that I very much wish it had are dedicated media keys and a USB passthrough, would rate 5 stars if it did. This keyboard has been a great investment for working from home! Makes the day-to-day much better.

    The keyboard works well and seems durable. The keystrokes are a bit too loud. A distraction in the days of continuous Skype calls.

    Sure this keyboard doesn't have all the bells and whistles of the more advanced mechanical keyboards. But the Romer-Gs feel pretty nice, they're almost as good as the dampened Cherry MX Clears in my CODE V3. I was looking for a home office keyboard just before the stay-at-home orders came down, and I think this ended up being a really good option considering I had been using the WASD CODE V3 at the office and wasn't exactly looking to spend another $200 on another CODE V3 for home.

    I type thousands of words a day and like a good tactile keyboard and this one does the job. The keys have a nice spring to them and I don't notice an annoying noise from the space bar that other people mentioned. This would be a 5 star keyboard if it weren't for the fact the first keyboard I ordered was defective. The keyboard would type "sssss" over and over unprompted. I had to take it in and exchange it for a new one. The new one works great but for a $70 keyboard I would expect perfection from the go.

    After using membrane keyboards for the past decade, I had forgotten how absolutely awesome mechanical keyboards were! My typing speed is noticeably faster now. So happy! It's not a loud clackity keyboard but I have my own office so I cannot tell how annoying it would be in cubicles or egads, open floor plan.
