Is Microsoft Natural Ergonomic Keyboard 4000 Mechanical

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).

It gives you the nice, clean feeling of a mechanical keyboard, but it's silent!!

Great entry level mechanical keyboard

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

Great mechanical keyboard. Love the preset lighting options.

Great mechanical keyboard for programming. Works great with Linux as well.

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.

This ergonomic mouse has helped with carl tunnel. It is angled just right so that your hand sits at a natural angle. It took a few minutes to get used to it, but once over the learning curve, it feels very natural. I like the ability to change the resolution on the fly to match what I need in different applications. I wish there was a driver so that I could program the buttons to use with Microsoft Flight Simulator.

I've had thumbs up for other bodies in the past and enjoy how it adds to the natural ergonomic grip. The price seems a bit high for what it is, but it is a very well-built and constructed bit of metal. If the added thumb purchase prevents a drop to pavement then it's a bargain! My only real complaint is the need to carry the Allen wrench when I wish to remove for flash use on the hot shoe. I'm certain I'll inevitably forget it or have in another bag when I need it.
