My old Ducky 9008s some keys had delay registering, so I desolder the affected switches and swapped with lesser used keys and they seem to be working  :thumbsup: . Pretty easy fix each switch has 4 points of solder 2 for the switch 2 for the LED. The LED solder was quite small & took some time to remove but with some patience can be done. Next time can try fixing my SS 7G which some keys double/triple register, should be easier since no LED to remove but don't know how the insides look yet.

Care to share more info like the wattage of your soldering iron? Did you bought from Taobao? I thought electronic items must have SIRIM certified sticker?    Otherwise I'll have to pay RM100 for the SIRIM sticker...
