Bought as a Christmas present for my boyfriend. She rejoices every day and grunts pretty, like a boar I have a mechanical-membrane ornata raiser, I didn’t even think that the difference was so noticeable, now I also want an optical-mechanical button My boyfriend spends a lot of time in games and if he used to be angry that the reaction from pressing is too low, then with this baby it no longer bothers him Conclusion: Gift this keyboard to your loved ones if you are a light sleeper and if the recipient enjoys clapping anything (Perfect if you have ADHD)
