“I have been using the keychron K2 V2 for more than a year so when this came out, I knew I had to get this. and boy I never imagined the smoothness and thock on this thing. I replaced the brown switches with lavender purples and it feels even better.”

Feker IK75 Pro vs Keychron K2 Pro: your questions
The Feker IK75 Pro has a significantly larger 10000mAh battery, while the Keychron K2 Pro has a 4000mAh battery. Based on the specifications, the Feker should offer longer use between charges for wireless operation.
The Feker IK75 Pro includes downloadable software for Windows and Mac, according to its vendor page. However, it does not support the open-source QMK or VIA firmware that the Keychron K2 Pro uses for more advanced reprogramming.
The connectivity listed for the Keychron K2 Pro is Bluetooth and wired. The vendor description and specifications do not mention a 2.4 GHz wireless mode, whereas the Feker IK75 Pro explicitly includes it.
The Keychron K2 Pro is the clear choice, as it explicitly supports ISO-UK, ISO-DE, ISO-FR, ISO-ES, and other ISO layouts. The Feker IK75 Pro is listed with an ANSI layout only.
Yes, both the Feker IK75 Pro and Keychron K2 Pro offer hot-swappable versions. The Keychron vendor notes that one specific 'Fully Assembled' version is not hot-swappable, so buyers must select the correct variant.
The Feker IK75 Pro uses a gasket mount, which its vendor states uses gaskets to cushion keystrokes for a softer feel and sound. The Keychron K2 Pro uses a tray mount (also listed as plate mount), which is a more traditional mounting style where the plate is screwed directly into the case.
Yes, both keyboards list Mac support. The Keychron K2 Pro vendor specifically mentions it includes keycaps for both Windows and macOS.
The Feker IK75 Pro is lighter at 850 grams, compared to the Keychron K2 Pro at 1070 grams. Combined with its larger battery, the Feker has an advantage for portability.
South-facing LEDs are positioned on the south side (bottom) of the switch. The Keychron K2 Pro features them, which prevents the LED from hitting the north wall of Cherry-profile keycaps, a common issue that can cause interference and a inconsistent feel.
Yes, the Keychron K2 Pro is available in a 'Barebone' kit version, which does not include switches or keycaps, allowing for complete customization.
The Feker IK75 Pro kit includes three layers of EVA and Poron foam. The Keychron K2 Pro (in its hot-swappable versions) includes sound-absorbing foam and a thick silicone dampening bottom pad.
