Product Details/Specs:

75% layout: It is a widely popular layout for professionals, as it is compact yet accommodates all the frequently needed keys. It is also preferred by gamers as it is a great space saver.

Durable Construction: The keyboard is built on a durable and fine Aluminum frame. It is built using the evolutionary aluminum alloy stamping process, which makes the mechanical switches invisible, adding to the overall design and appeal of the product. The process is much better than the conventional CNC machining process in maintaining a uniform body while keeping the overall weight under check. 

Ultra-thin Low profile: The keyboard is equipped with Gateron low profile switches and is only about 16mm at the thinnest portion, while it is only 21 mm at the thickest portion, which makes it highly ergonomic and portable. 

Thinnest PBT keycaps: To add to its low-profile design, this keyboard is equipped with the world’s first ultra-thin PBT keycaps. The ergonomically spherical keycap design is only 4.6 mm thick, which adds to the overall comfort of using this keyboard.

COAST Keycaps: The keycaps are made using an advanced dye-sublimation coloring technology, which makes the keycaps highly durable and long-lasting. The plastic quality is highly premium, which enhances the overall typing experience. These keycaps are known to maintain shine throughout a long period of time, making your keyboard always look new. COAST refers to the appealing color scheme of the keycaps, which depicts the daylight and twilight-colored keys on the seacoast. 

Switch Options: The keyboard comes in three Gateron switch options to choose from, Red, Blue, and Brown. All three of these are low-profile switches, which offer smaller travel distances and hence respond faster than the regular switches. 

  • Gateron Low-Profile Red: It is a linear switch without any feedback, and hence the smoothest option out of the available three switch types.
  • Gateron Low-Profile Blue: It offers click-style feedback and is the loudest of all three switch-type options.
  • Gateron Low-Profile Brown: This is a tactile switch, i.e., it offers a bump on registering the key press. It has a medium actuation force along with a lower travel distance.

Few years back I started to work from home, I needed a keyboard, I researched mechanical keyboard from A to Z. After that I needed a monitor, after that I needed a mouse, after that I needed desk, chair and other accessories. I did so much research and I figured this can't all go to waste and I started writing about what I know. Keyboards, Monitors, Mouses and other accessories. You can also at WolfofTablet where I cover a lot of stuff about iPads and Android Tablets. In the free time I like to play PS5 and iOS games.
