All keys on left side stopped working after 2 years. Unresponsive customer service. Not worth your money. Buy a better product from a more reputable seller.

Decent keyboard, but overpriced for the quality

Some good, some bad.After a few months, good value split keyboard with lots of options. Hard to find a split keyboard at this price point.Some things to watch out for! If you are a fast typer, you're going to struggle. It has a design flaw which makes it lack N-key rollover (NKRO), which means the keyboard can register every single keypress, no matter how many keys are pressed simultaneously. The lack of this feature causes "ghosting," where the keyboard misses or incorrectly registers unintended keypresses during rapid or complex commands, and is crucial for gaming, programming, and fast typing. If you're a faster typer, say over 50 WPM, then you're going to experience this problem, and it can be very frustrating. Another problem is if you use a lot of CMD + shortcuts, it will be tiring for your thumbs because they need to curl underneath the palm to reach the CMD key.

I have been using this keyboard 8+ hours per day, 5+ days per week, for almost 2 years now (I am a full time web developer). I originally bought this because 2 months into my job I was having intense wrist and finger pain, as well as hand cramping. After using this keyboard for a little while my pain pretty much disappeared.I will say that it was difficult to get used to at first; my typing speed went way down for awhile as I got used to it, but using it consistently helped. I also had a lot of trouble initially if I used a different keyboard (such as temporarily using my laptop keyboard) because my brain and fingers would have to readjust. I can say though that nowadays I don’t have this issue and can switch between them just fine.Some points to note:- I do not really use the shortcut buttons on the left side.- I really dislike that the Delete button and the Backspace buttons are the same size. Even after 2 years I have not gotten used to this and often use the wrong key because they are the same size and almost the same amount of reach.- I use the “medium” tenting setting without the padding and it feels great. It matches the natural angle of my wrists very well.- I do not have the halves separated very far, but I do angle them a bit away from each other because it feels most comfortable for me. I like the amount of flexibility it provides.- I really wish there was a keypad included. I find using the Function key to trigger the “keypad” in the middle of the keyboard to be very unintuitive and using the number row is awkward. I know they offer a detached 10-key pad, but $40 feels so overpriced and it requires an extra USB port.- I’m very happy that this didn’t require any additional software to work, as my job is very strict about this. If I remember correctly, I just plugged it in and it worked like any other keyboard.Overall I love this keyboard. It’s hard not to when it saved my wrists and hands. I also love how versatile it is with how you can physically configure it. If the Delete and Backspace keys were different sizes I would probably give it 5 stars, even without the keypad.

The keyboard misses too many strokes. When I strike the edge of the key with light touch I can almost miss 100% of strokes. The ergonomic features are ok, though I hope the tent can lock there without moving around. I don’t remember any keyboard I used are like this.
