As for the build of the Optilite MK872 is similar to the famous and classic design of Cooler Master QF Rapid. Solid plastic build and non-floating keys design are still preferred by most keyboard enthusiasts. It has a height of 3.5cm (default) and 4.5cm with stand off feet (measured from the edge of the keyboard up to the ESC keycap). Fantech chose the connectivity to be a non-removable braided cable maybe because to protect the board from water since it is claimed to be 100% waterproof.

Optilite MK872 has hotswappable optical SMD switches and currently has 2 variants available the black optical (linear, around 50-55g bottom out force using coins to test it since no info was given about the switch) and the blue optical (clicky but not as loud as an outemu blue switch with around 57g bottom out force). The switches are unbranded and doesn’t have a stabilizer in each key unlike the LK optical switches from Bloody and can be seen in a Razer Huntsman elite also. It is somewhat hard to remove the hotswappable switches with the use of the included switch puller so we recommend to use an IC puller instead and slowly pull out the switches and be careful not to damage the housing of the switch. The blue switches aren’t as loud as a typical blue switch and the black switch is somewhat stiff.

Note: Only hot-swap SMD optical switches are compatible with the Optilite MK872.

Stabs that are in the long keys (shift, enter and space) are also unbranded and has lots of rattle. You can easily eliminate the rattle by putting some dielectric grease in the stabs and wires.


The stock keycaps of the Optilite MK872 are ABS doubleshot OEM profile. The keycap side part is a bit glossy and not the same on the top part which shows inconsistency on the material. Optilite MK872’s keycap is only around 1mm and the sub legends (media keys and fantech logo on the spacebar) are pad printed which will worn off in time. You can easily change the keycaps with any keycap with a cherry mx stem and the layout is standard so you will not have any problems with the keycap compatibility.


According to Fantech world, the Optilite MK872 has a software for lighting customization but unfortunately we can’t find it in their website (www.fantechworld.com). The lighting modes however, can be change with the on-the-fly settings (FN + PSc, FN+ pause, etc) and the lighting speed via FN + Arrow keys. Optilite MK872 RGB SMD LEDs are bright and vibrant even in the dark. You can also set a monochrome light mode if you like it to be just in plain red, white or other color.

    Hey Kevin,
    Thanks for the review!
    If you still have this, have you figured out how to open/disassemble this keyboard? I only see the one screw at the back and cant find any leverage to take off the top housing…Im trying to get the stabilizers out to reduce that rattle and maybe put some foam in but im stuck 🙁

    1. Kevin Tan says:

      The case has notches on all sides. You can check some TKL like the ducky and old cooler master videos on how to disassemble it.

  2. Joko says:

    Is it possible to replace the switches with LK switches?

    1. Kevin Tan says:

      That I don’t know. I don’t have any spare LK switches

  3. Joko says:

    Do you know where I can buy optical switches? thanks

  4. abdulla says:

    Can you let us know which keys don’t have the stabilizers? And does it affect the feel of the keyboard a lot? I really appreciate this review. Really detailed.

    1. Kevin Tan says:

      Same keys just as a normal mech. All long keys have stabs

  5. jrayga says:

    What switches should i buy for this and where to buy if ever? Thanks for the review.

    1. Kevin Tan says:

      no. you need to disassemble and desolder

  6. Frits Welsing says:

    How the heck did you get those switches out. For the life of me there won’t even come a little bit of movement in them when I pull.

    1. Kevin Tan says:

      use an IC puller
