Microsoft Natural Ergonomic Keyboard 4000 F Keys

I've been using the Microsoft Natural Ergonomic Keyboard (4000?) for years. I've found that I need to see the keys more often and thought the old keyboard quite large. While looking for low-vision keyboards I found this illuminated model. I thought I'd never adapt to or like a flat keyboard like this but I was so wrong. This is the best keyboard I've ever used. Easy strike, silent, and I can see the keys without bright room lighting -- even without my glasses! A full numbers layout, easy extra function keys, great configuration, easy setup, and a sophisticated appearance. Love it. Highly recommended for everyone at all skill levels.

(This review was collected as part of a promotion.) I have used a microsoft surface keyboard for the past decade or so, but the keys are starting to wear off and since I got a new Lenovo IdeaPad I figured I'd try this keyboard combo too. I am pleasantly surprised by the premium quality, how quiet the keys are, and how quickly I was able to transition to it. So far, so good, and I'm pretty set in my ways.

I have been using both Microsoft and this mac keyboard. However while the keys on the surface keyboard are excellent. This keyboard is AMAZING! great for all day use strait out of the box. The magic here is in the keys them selves requiring very little to no force needed to trigger a key stroke. This keyboard is a pleasure to use and can see using this for years to come.

Exactly what I wanted from an ergonomic keyboard; compact, has the number keypad, and a good layout. Only downside is these are the squishy keys as opposed to the more tactile keys I like, but you can't have everything.

The ergonomic, lighted keyboard is everything I have been looking for. For years I bought other forms of lighted keyboards. One just had lights under the key section but the keys themselves didn't light up. One lit all the spaces between the keys but nothing ever lit up each letter on the keys. None of the other lighted keyboards were ergonomically shaped. This board gives you varying intensity of the lights, three colors of lights, lights on and off switch and is ergonomically configured. Somebody really put some thought into this keyboard.

3 illumination levels plus off allows for natural look in any lighting conditions -- or you can brighten it enough to say look at me! Smooth, quiet keys even when hit off center. Wired keyboard is proving to be faster and more accurate than my Logitech MX5500. (The mouse of that combo works find in conjunction with this keyboard).

This Keyboard has such a great feel, it feels very natural and smooth. The keys work with Mac and Non- Mac laptops/ PCs. You can connect up to 3 devices and it switches between devices almost instantly! The knob is very useful for my photography projects but also improves efficiency a lot. I can switch between tabs quickly, I can play music with just one tap, increase brightness and adjust the volume with just a twist of the knob. Although a bit pricey, it’s well worth it! 11/10

It is the only compact ergonomic keyboard that seems to be available, that is structurally sound (without bending).

Pen has long battery life, natural feel, and is a must have accessory for the Microsoft Surface line of products. Shipping was quick!

A fantastic and almost necessary accessory, as it allows for an ergonomic and natural approach to operating your camera. I have an a7iii and love it! The stop/start record button is in reach but just high enough where I don't accidentally hit it. Overall, this allows me to operate the camera with my right hand, and the lens with my left hand.
