While with the K70 RGB RAPIDFIRE sporting regular MX Speed switches we needed a bit of adjustment time due to the fast 1.2mm mechanical actuation distance and was sometimes difficult typing documents without making mistakes, with the K70 RGB MK.2 Low Profile we felt that no training time was needed. We are dealing with a 35% lower key height versus the regular Speed switch and people that enjoy typing on laptop keyboards will really enjoy the new LP series. Another aspect that we did really enjoy is that the LP Speed switches are quiet, if not more quiet versus the regular MX Silent variant.
