The Mk21 keyboard feet risers are securely hinged so, they don't flop around when extended. The feet risers also feature grippy rubber pads that prevents the keyboard from sliding around while elvated. There are 8 solid colors (red, orange, yellow, cyan, blue, purple, white, green) to choose from, as well as different lighting effects, including single color lighting effects and multicolor lighting effects. The single color lighting effects can be manually changed. There is also a game mode (lights up the WASD keys) and a custom mode for customizing key lighting. The speed of the lighting effect can be increased and decreased also from the keyboard. To toggle between solid color options on the Magic Refiner Mk21, you have to press Fn+Tab key. The base of the Mk25 keyboard is slightly angled but the keybed sits almost flat so, the top row of keys is about the same height (4cm high) as the bottom row of keys. With the feet risers extended, the height of the the top row of keys gets elevated to 4.5cm high (using the shortest feet) and 5.5cm high (with longest feet risers). The Mk25 keyboard measures 29.5cm long and 11cm wide. There are a total of 15 lighting modes, ranging from single solid colors, multi-color and wave effects. There is also a game mode, which lights up the WASD keys on the keyboard. This is handy since the Mk25 keyboard doesn't have navigational arrows.

The Magic Refiner Mk21 measures 29.3cm long, 10cm wide, 4cm high (including the top row of keys). When the feet risers are extended, the height goes up to 4.5cm (shortest feet) and 5cm (longest feet). Total weight is 549 grams. The Magic Refiner Mk21 uses LC mechanical switches, which are basically clones of Gateron optical blue switches with the exact same feel as Cherry MX Blue switches so, they have a high operating force with a short actuation travel (0.15 mm). The Magic Refiner Mk21 keyboard has on-board functions too. You can control the RGB lighting and brightness, which can be increased and decreased in 20% increments from 0%, 20%, 40%, 60%, 80% and 100%. The lowest brightness setting (0%) turns off the RGB lighting. You can also turn off the RGB lighting manually by manually cycling between the color options until you get to the "off" option. The bottom base of the Magic Refiner Mk21 has a gradient design, which naturally keeps the keyboard at an angle. The keyboard can be elavated higher, thanks to the feet risers. Most computer keyboards have feet risers but the Magic Refiner Mk21 has dual feet risers, which allows you to adjust the height of the keyboard in two levels. The Magic Refiner Mk21 is compatible with Windows computers (Windows XP, Windows Vista, Windows 7 and Windows 8) and Mac comuters with USB-A ports, which include the old MacBook Air, new Mac Mini, iMacs, iMac Pro, and the 2013 Mac Pro.The Mk21 uses plate-mounted dummy switch stabilizers, which look like Cherry style stabilizers but without the stabilizer bar. This makes cleaning the keyboard much easier and less fiddly when replacing the keycaps. Plate-mounted stabilizers perform well, although PCB-mounted screw in stabilizers offer the best stability. The Magic Refiner Mk25 Keyboard has a plastic body shell with a metal top plate and non-hot swap BSUN brown leaf switches, which have a tactile, light travel actuation similar to Gateron brown switches. On the base of the Magic Refiner Mk25 keyboard, there are four anti-skid rubber strips and dual feet risers that let you adjust the height of the Mk25 keyboard in two levels. The feet risers are made of plastic and are securely hinged so, they do not wobble. The feet risers also integrate grippy rubber pads that prevent the keyboard from sliding off when the feet risers are extended.
