I have just purchased this keyboard and I am impressed by the build quality. Like many people have commented the software leaves a lot to be desired as it is very buggy.
Before purchasing the keyboard I read quite a few reviews and the majority were very positive but after purchasing the keyboard I have read quite a few negative comments on sites like Amazon that the switches fail after a few months use resulting in key chatter and bouncing. Do the Kailh switches have a high failure rate? They are supposed to be rated at 50 million key presses but fail after a few months? I'm now very concerned about the reliability of this keyboard. What is the return rate on these? I know it has a five year warranty but the cost of return postage is high and I would not want a second hand replacement keyboard. Not sure if to return this now.
