I'm on my 5th Corsair keyboard with Cherry switches - they eventually always start double clicking, Corsair replaces the keyboard under warranty, rinse and repeat. It's awful from electronics waste point of view, but I just don't see those as very reliable products.
Curious. I'm on my 1st Corsair with Cherry switches. Bought it second-hand in as-new condition from a mate about 5 years ago, gave it its second clean last night, removed 1.5kg of cat fur, and it's as-new again.
It's an absolute tank and the ONLY thing I'd give it up for is a mint-condition Model M.
