I used these for a build and have been liking them a lot. They have a very unique feel, with strong tactility and a bit of weight near the bottom-out, which somehow gives them a bouncy feel which is appropriate given the name.When I tested one which was unlubed, I worried it could end up slightly on the stiff side for my tastes, but with a light lube with GPL 106 (I'm sure whatever lube you prefer will work fine), the extra smoothness made the weight feel about right for me.The tactility has a very definite feel and gives good feedback while typing text. I feel like I rarely have accidental key-presses with these. The slightly stiffer tactility might not be my first choice for gaming, though, where I prefer a lighter press.
