Ergonomic Keyboard 4000 Keys Not Working

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.

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.

Keyboard keys are solid and quite. Like working in low lite,keys are perfect for this.

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!

With the Covid pandemic continuing, and my working remotely from home, I decided to buy an ergonomic keyboard with an ergonomic mouse, and trying to find one similar to the one I use at work was almost impossible until I stumbled upon these. They were shipped quickly and very easy to set up. I'm free from cords! I love them.

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

This keyboard is exactly what I was looking for for my home office. The illuminated keys are great for working in low light. The keyboard feels sturdy and well made and it looks good.

Got this keyboard to work with a Dell XPS laptop for both working while docked and for travel. It's well made and the keys have excellent response and travel for touch typing. The illumination of the keys is easy to control right from the keyboard. No drivers to install. The only odd item is choice of font for the keys. It's not a deal breaker but odd. Also the print screen key is labeled PS, scroll lock SL, etc. Why they changed labeling conventions from other keyboards is mystifying. But, that being said, great keyboard.

This is the second keyboard like this I had. When it stopped working I was really upset till I seen it on here It makes it so easy to find the keys' I just love it and would recommend it to everyone
