+--- +template: +url: ducky-one-2 +title: The Ducky One 2 SF +subtitle: I fell for the mechanical keyboard meme +date: 2020-08-22 +--- + +Thanks to the pandemic yada yada I've been working from home (and +attending college from home), and I figured my WFH setup could use an +upgrade. Unfortuntely, the choices for mechanical keyboards in India are +fairly limited. All imports from China don't get through, and imports +from elsewhere have a _fat_ duty slapped on it -- sometimes up to +300%[^1]. It's obscene! + +[^1]: https://www.reddit.com/r/mkindia/comments/hzyoof/i_see_many_spreading_misinformation_about_import/ + +The only reliable source I've found (and folks on +[r/mkindia](https://reddit.com/r/mkindia) will concur), is +[Meckeys](https://meckeys.com). They aren't particularly abundant in +variety, but there's some decent prebuilts that you can pick up on +there -- and I copped the Ducky One 2 SF. + + + +It's a 65% board, so unlike standard 60% boards, this comes with arrow +keys and the `Del`, `PgUp` and `PgDn` keys. I don't _really_ need the +arrow keys, but they do come handy on the occasion -- like scrolling, +for example. Since this board lacks the function row, the `Esc` and the +`~` keys are merged. I have to hit `Shift + Esc` for tilde (same action +as usual), and `Fn + Esc` for the backtick. Takes a bit of relearning, +but it's manageable. + + + +The key switches I went with were the Cherry MX Speed Silvers -- like +Reds but actuate a bit faster. As it's my first ever mechanical +keyboard, I don't really have anything to compare it against. It feels +_great_, but it was pretty jarring initially because even the slightest +touch (with the palm for instance), would cause a key to actuate, leading +to typos. Again, just a matter of getting accustomed to it; all smooth +sailing after. Why did I pick the Speed Silvers? The other switch +options were out of stock. + +That said, I think I really quite like linear switches. They're not +_too_ noisy, and they feel just right. I haven't noticed any great +improvement in my typing speeds though -- I still maintain an average of +90-100 WPM. + +The One 2 SF is fully RGB, i.e. each key is individually lit. Not that +I make big use it. I have it set to plain white, and only light up under +the key I'm currently pressing. Yes, this also makes it incredibly easy +for people to shoulder-peek your passwords. I certainly won't be using +it outside home. + +The keyboard itself cost 9599 INR, which is about 128 USD. Meckeys +took exactly 10 days to ship it (3rd Aug - 13th Aug). Overall, it's +a lovely keyboard, and I _cannot_ type on my laptop's low-travel +chiclet-style keyboard, again. There's just no going back.
