Customers also love the typewriter touch of the keys and find it extremely easy to type on. They mention that there is no flex when typing and that there's no wobble or mush.

    Brilliant mechanical Switch Keyboard
    1 Year Later: Absolutely NO flaws. Getting another one for a second desk at work. Getting the 'gaming' model with RGB lighting for the house. The Romer switches are the perfect balance between feel and sound.O. M. G. Got in my Logitech K840 keyboard today.Absolutely brilliant key feel - anodized brushed aluminum key caps with laser etched letters. New Japanese mechanical switches. Just the right click to know you fired a key press, no louder that a rubber dome Lenovo keyboard. Slightly louder than the $5 Kensington ones they pass out at work.But the finish, the quality of this board is an order of magnitude better than the price point. I have found the grail, antd it's is Logitech! Extraordinary price point - a full half less than even the cheapest 'gaming; keyboards without the LED gauche -- very clean and professional looking!Please keep in mind, for 34 years I have typed exclusively on IBM Model M keyboards. I learned to type on an IBM Selectric. I learned to code on the OG a Apple mechanical keyboards. I have 10 IBM Model M keyboards in storage, just incase I ever break one. Literally a thousand year supply of Model M keyboards.This Logiteck oustrips them all.Works just fine on Macintosh, if you can remember the windows key is the Command key in Mac.All I wish is it had a Kensignton lock slot on it; I guarantee if I leave this out at work while I'm on vacation it will get 'procured'. Now to find a case big enough to carry it back and forth to home.

    5.0 out of 5 stars Great for typing!
    Reviewed in the United States on August 6, 2020
    I love this keyboard! This is my first mechanical keyboard and I'm hooked. I've used it just about every day for a month now. I understand that it probably doesn't have the greatest switches. I hear that cherry MX switches are the way to go. But, I went from a cheap, all-plastic Lenovo membrane style keyboard that was mushy to this, and the quality is just amazing.

    I would not recommend this for gaming though you certainly could use it for that. It's just a bare bone keyboard that is great for typing. I type a ton, and this is a major upgrade from a membrane style keyboard.

    The deck is sturdy aluminum and there is no flex when typing. The keys on this have a good amount of travel. It's not a super loud keyboard, but it does have a satisfying click when typing. If you do buy one, make sure to get a palm rest. It does sit a little high.
