    Before choosing what type of mechanical or optical switch, we need to understand it is mostly about preference. You need to look into what will work best for you and what you will use your keyboard for the most. Our Epomaker GK series, and some of our other keyboards allow for hotswappability. This means that even if you dislike the current switch you bought, you can swap it to another switch. Which switch you can swap to depends on your keyboard type.

    Still no sign of my keyboard

    Despite contacting Epomaker twice after the delivery estimate passed and being told the shipment was on its way, there is still no sign of it. Both times, customer services fobbed me off with the shipping reference, which the shipping company repeatedly deleted information from. The shipping company has now admitted it has no idea where the keyboard is, but that I should wait until mid-August before instituting a claim. Which Epomaker will only refund me 50% of what I paid. Beginning to feel distinctly ripped off.


    Thank you for leaving a review here.

    We are so sorry that you have not received the package.

    Our support keeps following your package but has not received updates from the shipping company yet. We will send you updates once we receive any.

    Thank you for your understanding.

    Kind regards,
    Epomaker Team
