Honestly not good when not lubed. Out of all my switches these sound bad even with a board with double-gasket. With a vanilla GMMK the spring crunch makes them even worse and they feel stiffer than switches that are actually heavier.

Add some lube to them, and they feel and sound great. The only thing is that you will find that a few of them have pingy leaf springs, which can be hard to fix.

When not lubed, is a little scratchy. Also has a questionable quality control. Other than that, best tactile out there
