Used many keyboards in my time and DasKeyboards blow the others out of the water, much higher build quality than any other example I've used, which includes Ducky Shine 3 (lights blew in weeks, doesn't feel high quality), Razer Black Widow (definitely feels low quality, mine didn't break but two other friends have in <1 year), had good experiences with Logitech keyboards in terms of running long term without problems but don't feel as nice/high quality as das (especially newer models), Corsair keyboards feel alright in terms of quality/solidness (still not as high as Das, but haven't used one long term so can't comment on long term)
Probably others I'm not recalling but they seem to be the main ones brought up in the thread, would not hesitate to recommend Das to anybody.
