Why should you buy a Mechanical Keyboard? Cheaper keyboards usually incorporate a rubber-dome or a membrane switch system wherein a keypress pushes onto a silicone dome, connecting the circuit to register what the user is typing. These often require a large amount of force for actuation and give off mushy feedback due to the silicon underneath. These are relatively silent and don’t offer audible feedback, while the overall lifespan of the keys is also comparatively shorter.
When you press a key on a mechanical keyboard, an actual physical switch, including a spring-based pushback mechanism, comes into play. Depending on the type of key switch, you get a certain tactile or linear feedback as you type along. While that in itself makes a huge difference, these switches also last really long, with certain manufacturers claiming up to 50-80 million keystrokes.
In short, mechanical keyboards offer a longer shelf life, and you can expect a much better typing experience thanks to the wide variety of switch options.
Glad to see Redragon getting a mention as I've been using mine for a few years without any issues.
