Tt eSPORTS Knucker Review @ Vortez
 

We would typically expect to see a mid-range membrane gaming keyboard at this price point, yet the KNUCKER spurns mere membrane switches. Instead Tt eSPORTS are utilising what they call a Plunger design - a hybrid of traditional membrane and mechanical mechanisms intended to generate a much more consistent and tactile response than typical membrane keyboards. The design should also increase keyboard durability significantly - they are rating each plunger switch for a life expectancy of up to 15 million keystrokes, a vast improvement over standard membrane keyboards.
