Microsoft Ergonomic Keyboard 4000 Mouse

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 keyboard works well with Microsoft's x-box console. I also use the M720 mouse at the same time!

Very reliable, really nice, ergonomic mouse and solid keyboard

I used to own a Kensington wireless mouse because I liked how it looked. But it had lousy wireless connectivity and it constantly dropped its signal for no apparent reason. Seeking to replace it, I came across the Microsoft mouse at my neighborhood consumer electronics retailer. I found this same mouse at B&H for $20 less. I love this mouse. It's got a stylish appearance, the wireless signal is rock solid...no more dropped connections and it tracks great. I also like how I can easily power it off to save battery life. The only drawback is that it requires its own USB antenna so when you're using Microsoft's equally stylish wireless keyboard, you're using up 2 USB ports: one for the mouse antenna and one for the keyboard antenna

As soon as I connect, the computer immediately detected the Microsoft surface mouse and keyboard. It's fast and no has delay. Does not fail even in situations of intense use such as line drawing or fast typing.

(This review was collected as part of a promotion.) Both keyboard and mouse are very ergonomic. It solved my fingers pains changing to the Lenovo 300 Combo Wireless. Also, using the keyboard is very smooth, once it does not make any annoying sound. Highly recommended.

Home use. Great ergonomic mouse!

This is a very comfortable and ergonomic mouse pad.

great price and works great, better than Microsoft mouse

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