DSI Left Handed Mechanical Keyboard Cherry MX Red KB-DCK-LH104-V2

Bought this keyboard for CAD work so I could easily use the number pad with my left hand while keeping my right hand in the mouse. It works great for it. Only complaint would be the noise of the keyboard. It is not loud like a keyboard with Cherry Blue switches but there is definitely a hollow spring noise if you are typing swiftly. Without lubing or swapping switches, it doesn't seem possible to remedy this but it is not a deal breaker at all. The other complaint I have is some of the keys can get stuck down. "Page Up", "Page Down", "Pause" and "ESC" are the main offenders. Loosening the keyboard housing then tighten it again seemed to fix the issue.

I bought this keyboard in June 2015. I'm writing this review in May 2021 so I have been using this keyboard as my daily work computer for 6 years. I basically live on my computer >6 hours a day so this keyboard has seen a lot of use.I bought this keyboard because I am a lefty and wanted a number pad on the left side of my desk. I use excel every day and this made it much easier to type numbers while being able to use the mouse with my right hand to change cells. It also allows me to use the arrow keys and mouse without removing my hand from the mouse. This is a HUGE advantage for anyone who makes use of a number pad often. I would recommend a left-handed number pad / arrow setup to anyone who preforms a lot of tasks on a number pad.The arrow keys are moved to the left as well which as taken some getting used to, but if you force yourself to switch to this keyboard it will become 2nd nature to use those keys with you left hand. At this point I can switch between this keyboard and a normal one with no issue.The keycaps are fine, they have held up fine with the exception of the spacebar key which has lost it's texture and become smooth. Not an issue for me.The cherry red switches seem great, I have had no issue with this switches. I use cherry red switches due to a knuckle injury as it reduces the stress on my knuckle (which has arthritis now from the injury).So in summary. This keyboard has held up to 6 years of daily use in an office environment. The key caps and switches have worked flawlessly. It will take some time to get used to a left-handed keyboard, but I think it would help anyone to be more productive (right-handed or left-handed)

Thanks to an understanding employer, I've have had one of these keyboards at work for over 10 years. Working from home over the past year made me realize how much of an impact it has had on my productivity and well-being. Purchased a 2nd for my home office and happy I did. It's amazing what the right tool does for your life.If you are left-handed, ambidextrous or have physical challenges which require you to key left-handed, I encourage you to give this keyboard a try. Yes, it's corded but I have yet to find a cordless keyboard with a complete 10-key on the left and the major keys right where you need them. I suspect its durability is also due to that heavier, corded construction.

This is a great ergonomic keyboard for people who use a mouse with the right hand. By moving the arrow cluster and numpad to the left side of the keyboard, it frees up room for the mouse on the right side. I can sit centered to the keyboard's home row and the mouse lines up perfectly for my right hand. I do a lot of work on the computer, so not having to reach for the mouse really helps my wrist and back. In my opinion, all RIGHT handed keyboards should be designed this way.The Cherry MX Red switches are fantastic. They're quiet for mechanical keys and require very little force to press while still springing back up instantly. Prior to this keyboard, I was using a Ducky mechanical keyboard with Cherry MX Brown switches. The brown switches provide a tactile bump so you know when the key has been pushed far enough to register. Most people recommend browns for typing, but I'd have to disagree after trying out the reds. The reds just provide linear resistance without the tactile bump, but I feel like I can type much faster with the Reds. They require less force to register and spring back up faster and quieter. Though, it's also fairly easy to hit keys without intending to, since you really only need to push the keys down about a third of the way before it registers.This keyboard still has some flaws, though. The supposedly left-handed numpad is not meant for left-handed use at all. The way keyboard numpads are designed, the 0 key should be pressed by the thumb and the enter and + keys should be pressed by the pinky. But by moving the numpad to the left hand side without mirroring the key layout, the keys do not line up with their respective fingers. It baffles me why DSI did not mirror the numpad, maybe their designers have two right hands? I would prefer spending a few minutes to relearn a mirrored numpad than have to contort my fingers to hit keys meant to be used with the opposite hand.Another issue is the backspace key is tiny while the enter key is huge. Who even uses this layout anymore?! Practically every keyboard out there nowadays increases the size of the back space key and replaces part of the enter key with the backslash. I use the backspace key much more than the enter key, and having to stretch my pinky to the furthest corner to hit a tiny key is pretty cumbersome. The enter key is easy enough to hit as it is, it doesn't need to be 5 times the size of other keys. I guess the positive side to this is that it forces me type with fewer errors so I don't have to use the backspace key as often.Lastly, the keyboard bezel is much larger than it needs to be. There's a 3/4 inch bezel around the entire keyboard, which ends up taking valuable desk space. Maybe it's needed for structural support, but then they could have used another material than just plastic. My Ducky mechanical keyboard, which I got for $20 less than this keyboard, is made from metal. I'm sure they could afford to use a better material.Even with these issues, I still believe this is the best keyboard for right handers available. The Cherry MX Red switches and the freed up space on the right side of the keyboard are wonderful features. I'm glad DSI decided to make this keyboard, even though there's not a very big market for it. Hopefully, they will release another iteration with a better numpad layout and backspace keys. If you're in the market for a mechanical keyboard, I would highly recommend this one!

Works well

(edit) - As of June, 2015, they changed this keyboard (its switches). The older reviews aren't accurate. The keys used to be fast, springy, and clacky. Now they are slower and quiet. Ironically, I was purchasing a second one now in case they ruined or changed this keyboard in the future. The old keyboard was so great, and I'm not even a lefty. Too late. So I'm updating my review and rating.The keyboard is cheaper price-wise, but you're paying for a cheaper keyboard. In my opinion, they changed to cheaper switches and didn't update their advertising. They just put the keyboard on sale, making you think you're getting a deal. This fooled me. I'm downrating from 4 stars to two stars for this and because the keyboard is now overrated.
