[Knob] If you spend a lot of your life writing, like I do, you may find that you long for the great IBM selectric keyboards that gave you a mechanical feedback. Today's keyboards are uniformly mushy, with a few exceptions, such as Lenovo's famous keyboards. So after reading the reviews I sprung for the Das Keyboard 43 professional. It has a great response and feel. Nice click but not too loud. Would not recommend if you work in a quiet spot and don't want to wake up roommates!

[USB-A ] My older work-from-home keyboard (as a full-time programmer) started to have some sticking keys, so I decided to splurge and buy myself a good one. I first learned to touch-type on a manual typewriter when I was young, and most modern (post-1990's) keyboards still just feel wrong. This feels excellent, and my typing speed is getting back to what it should be. Not having to worry about typos due to lack of rollover is also very nice.

It's also about as compact as a full-size keyboard with a numeric pad can be: no fat borders or wrist rests (ugh) at the edges. The slightly recessed sleep button is very convenient for shutting down at night. My only quibble is that the LED for the Numeric Lock is annoyingly bright; after a couple layers of trimmed post-it note on it, the LED is just bright enough to be useful. (And I don't mind the brightness of the Caps Lock LED, because I've been known to hit that key by mistake.)

Overall, excellent.

[Mechanical] Great tactile feel, love the integrated functions in the top right corner, and very comfortable to use! Best one for any use, gaming, editing, etc.

[4.73 lb] This keyboard is the ultimate typing experience compared to any other keyboard Ive tried. I had a cheap keyboard with brown switches, cause I thought the blues would be too loud for my office. However, the brown switches barely had any tactile feedback, they were actually worse than some silicone dome keyboards from Gearhead. So I got this keyboard and my office coworkers actually prefer this sound, it is rather clicky, but is missing the clunky sound of bottoming out, which was a problem with the cheap keyboard.

One problem though; the USB hub doesnt work on the one I got. If I plug something in the hub, it says theres insufficient power and it doesnt mount the device. I contacted customer support and they got me to do a firmware update, but that didnt solve the problem. They told me I can request an exchange through B&H, but I didnt want to do without it for that long, so I just dont use the hub, which I probably wouldnt have anyway.

[Detachable] I'm a programmer and have had a CM Storm for 10 years. The printing was wearing off and I decided I was due for a new keyboard. I had a coupon and decided to get a Logitech g915. Big mistake. That's a bad keyboard. Short keystrokes, and seems very vulnerable to windows updates (Loses connectivity except for the volume wheel and requires a reboot to fix). Gave the Logitech to my wife ;-) and got the Das for me. Perfect in every way.

[Mechanical] Purchased the blue switch before this and was just too clicky for me. This one is a perfect tactical keyboard, responsive, comfortable, and beautiful.

[45 g] After rotating through a handful of membrane boards, I bought this keyboard for work and am absolutely loving it. I had never used a mechanical keyboard before but found that this board is an absolute pleasure to type on. The keys (mx brown) have a great feel and are not so loud that they drive my office-mate crazy with all the clicking. Highly recommend!
