I'm a huge fan of this keyboard. For the price($46) I absolutely think it's unbeatable. The tactile feedback is the best I've ever experienced (30+ years of typing on various keyboards for work and play). It nice and clicky like a traditional blue-switch mechanical keyboards but not nearly as loud. Even better, it has more resistance than them and also has sort of a 'pop' to its compression when pressing down on the keys (the membrane's contribution).
Think of it sort of like a compound bow; lots of resistance at the initial pull, but once you push past a certain threshold it suddenly pops back to full extension, due to the momentum of pulling past the hardest part of the string's resistance. That's this keyboard! So freakin' sweet.... I can type on it all day and be happy. Keep in mind, a quality membrane keyboard, such as my old keyboard, Logitech Illuminated Ultrathin Keyboard K740 with Laser-etched Backlit Keyboard and Soft-touch Palm Rest, will give you this feeling as well, but it won't have that added mechanical switch feeling and audible 'click'. Really, it's the marriage between the two techs that make this so wonderful.
