“This is my first serious mechanical keyboard. It sounds and feels great stock. You don't really need to mod it, but if you do, i think it will sounds amazing. 0 regrets, im very satisfied.”
“I received this item broken: switches, plate, box, stabilizers- everything was either broken or not assembled properly.”
