Happy Hacking Keyboard Professional 2 vs Corsair Vengeance K70 RGB

This keyboard uses a 60% layout that forgoes unneeded keys and merges the extra set of keys into the Fn layer. This mimics the behaviour found on most laptops due to size restrictions. Despite this, the more commonly used keys are left intact so that one does not feel too unfamiliar with the more compact layout. In addition to reducing the keyboard's size, it makes accessing virtually every key on the keyboard a breeze.

The Happy Hacking Keyboard Professional 2 is a very well built keyboard that uses materials that give it a tough body resistant to bending.

This keyboard comes with the standard DIP switches to modify key behavior, but you can also completly swap out the controller board or even fork the TMK firmware to make your own keybindings in the firmware. Also available is the TMK controller board custom made for HHKB users.

Eiiti Wada (a Japanese computer pioneer), the co-developer of this keyboard, is a UNIX user and wanted to make life easier for programmers, particularly vim and emacs. He aimed for a keyboard layout that allowed fingers to stay in the home row most of the time. For example, he placed the Control key where the Caps Lock traditionally is. Most *nix users and general power users know that Control is used more often than Caps Lock for various shortcuts. Therefore, this key repositioning makes sense, since it makes access easier, using the pinky fingers while keeping one's hand on the "home row" of keys.

This keyboard’s keys use Topre switches, which have a smooth, interesting feel: each key’s resistance is quickly lost once it starts being pressed. This sensation is accompanied by a unique and pleasantly organic “thock” sound. These hybrid switches have both a rubber dome and a spring which create the initial tactile bump feel and subsequent continuous action. If you want, these switches can be silenced, either by the manufacturer before purchasing or by following some DIY steps (easy to do, but time-consuming).

PBT plastic is a very brittle material that is able to withstand high temperatures, doesn't yellow or wear out easily. The dye sublimation process ensures the inscriptions don't wear off easily (compared to pad printed ABS, for example). This process usually requires keycaps to withstand high amounts of heat for the ink to transfer from one material to the other, something that's not possible with other commonly used plastics, like ABS. Dye-sublimated inscriptions are also better than laser, etched, or engraved inscriptions in the sense that they don't get dirt or dust as easily.

The positioning of the numpad on traditional keyboards forces users to keep the mouse far on the right-hand side. With this keyboard's compact layout, a more ergonomic workspace can be created by allowing the mouse to be placed closer.

Even though there aren't dedicated keys for these functions, they can be easily used by pressing an easy-to-reach Fn key, placed just below Enter. Functions accessible via the Fn key are printed on the front of the keycap.

The K70 uses Cherry MX Red key switches, which deliver a smooth, linear key response with a wide actuation zone. They have the responsiveness you need for perfectly executing double and triple taps, and there’s no audible click or tactile “bump.”

The Vengeances K70 RGB has a 16.8 color backlighting system that allows for so many color customization options that the possibilities are most likely endless.

Special keys are of textured, red colors, which facilitates access to common functions without looking at the keyboard (for example, numbers 1 through 6, and WASD keys).

Thanks to an included small wrench, that can be used to remove and replace the keys, the K70 is easy to partially disassemble and clean.

The size of the keys is ideal for standard to bigger sized hands.
