for I , the feature most important in a keyboard be the feel of the key and durability of construction -lrb- so that it 'll last -rrb- . in these two area , this keyboard be significantly better than any other I have use or even hear of ... and I have use a \* lot \* of keyboard . it be really no contest . you can not really convey to someone how it feel until you try one . all I can really say about it : if you type a lot and like to type fast , this thing be most likely go to please you \* immensely \* . as for construction quality , most feedback I have see hint that these last a very long time except in minor way like key label wear -lrb- mine 's already show small crack in the letter from just a few week of use -rrb- . and I be definitely go to put the overall durability of this thing to the test . I type a lot , and I type fast . if something go wrong I 'll add commentary here . where this keyboard struggle be in some feature you would reasonably expect from it give its pricetag : a ergonomic design version , backlit key , and a more stable usb setup -lrb- give that it be part of the design at least -rrb- . ergonomically , this keyboard could not be less so : it have a razor-straight layout that make you use the muscle on the outside of you forearm -lrb- as you would expect -rrb- , and most edge that be not on key be sharp instead of round . you 'll most likely want a wrist wrest for this at least . it be here in these weak area that I 'll expect progress from this manufacturer : it should not be difficult at all to put out a more ergonomic , backlit , silent version of this model for a very similar price . as a matter of fact , I 'll most likely expect that much next time I look at buy another DAS , and if I can not find something like that I 'll probably look elsewhere . one last thing . a lot of feedback I read on this keyboard center around the `` silent '' part of the name . lot of people seem to expect a very silent keyboard . the problem for I be in how I buy thing -- when I spend this much money , I want to know exactly what I be buy . it only take a little bit of digging to discover what the `` silent '' refer to -- it be in comparison to the non-silent model from this maker -lrb- which pump out significantly more sound -rrb- . do yourself a favor if you be consider pull the trigger on this -- know that it be not very silent at all . from my guesstimate , it be somewhere around 30ish % louder than a normal keyboard .
