Ergonomic Keyboard 4000 For Sale

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.

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

Very reliable, really nice, ergonomic mouse and solid keyboard

I'm using this keyboard with Nuendo. The shortcuts are a great time saver. It's ergonomic. Highly recommend it.

It was quick and easy to install. It glides in and out nicely. My large, ergonomic keyboard does not fit well but I am making due. I'm not sure about the slide out mouse holder however I'm trying it out.

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.

Bought two of these to mount halves of an ergonomic keyboard to (yeah, also need tablet mounts to actually hold the keyboard halves). Rock solid platform even with me mashing on the keys all day.

I just started working from home for the first time and knew I needed an ergonomic keyboard. I also didn't want to break the bank. The Logitech Wave Keys is perfect!

Improves ergonomic options - especially when combined with an external keyboard or monitor. Well made, typical Apple quality construction...
