this be a great keyboard in theory . I love the feel and consistency of the key , and the variability of the backlight . I can do some serious typing on this keyboard and enjoy every moment of it . well , assume I remove all of the macro key , which I do . they get in the way -- I align my hand by feel , base on where my left pinky find the edge of the last row of key . if you stick a extra column of key there , I line up too far to the left and disaster and frustration ensue . for a day or so I try to jam my pinky in the crevasse between the macro key and the normal key , but that be uncomfortable and make it difficult to hit Tab . then I try to position my hand in a more traditional typing posture , which do not work very well . I could have stick with it and re-learn to type , but I like the way I type now and do not want to change , so I pop off the macro key and all be well . only downside be , the blue led be pretty bright without key to obscure they . I might paint or tape over they . issue number two be that in low light , the painting on the key be very hard to see because it be dark gray . the light-up portion of the key be fine -- perfect , in fact . the altered font do not bother I at all . what do bother I be that I have to lean in and closely examine the key to figure out what they shift function be because I can not see they . Blue lead + dark gray paint + black key = very poor usability and visibility , especially in low or no light situation . lastly , my keyboard arrive defective , but it take a day or two to notice how . the spacebar be just a little too loose , so when I hit it at any kind of angle with my thumb , it will grind against the x or the m key , depend on which thumb I use . this cause superfluous xe and m , cause I lot of frustration . I try to adjust the spacebar to see if it be out of alignment or something -- there be nothing I can do , it be just not work right and have to go back . so I have request a exchange from Amazon . unfortunately , it be out of stock and I be still wait for a new one after two week . in summary , I like this keyboard and can not imagine use anything else anymore . I just wish it be better design and better manufacture .
