FAQ

AULA F75 Max vs Redragon UCAL K673 Pro: your questions

Based on specifications, the AULA F75 Max has a larger 4000mAh battery, while the Redragon K673 Pro is listed with a 3000mAh battery. The AULA's vendor page claims up to 30.5 hours with backlight on. No specific runtime is given for the Redragon.

The polling rate for the Redragon UCAL K673 Pro is not stated in the provided specifications. The AULA F75 Max explicitly lists a 1000Hz polling rate for both wired and wireless modes.

Yes, both the AULA F75 Max and Redragon K673 Pro feature hot-swappable sockets. The AULA's listing mentions compatibility with 3-pin and 5-pin switches, while Redragon's description states its socket is compatible with nearly all 3-pin and 5-pin switches.

The AULA F75 Max has several advantages for modders. It includes screw-in stabilizers, which are more stable than clip-in types. It also features a pre-installed layered foam system (IXPE pad, PET pad) and south-facing RGB LEDs that don't interfere with many aftermarket keycap sets.

According to the vendor description, the AULA F75 Max's TFT screen is customizable and can display GIFs, photos, keyboard lighting controls, battery level, connectivity status, and the date and time. It is controlled through dedicated software.

Yes, the specifications for both the AULA F75 Max and the Redragon UCAL K673 Pro list PBT as the keycap material. PBT plastic is generally more durable and resistant to shine than ABS.

The Redragon K673 Pro is listed at 1200 grams (1.2kg), while the AULA F75 Max is listed at 960 grams (0.96kg). The Redragon is the heavier of the two.

The AULA F75 Max listing includes 'Mac/Win Support' in its extra features. The Redragon K673 Pro specifications do not explicitly mention Mac compatibility, though it may function with basic key inputs via USB or Bluetooth.

Both keyboards use a gasket mount style. This design uses silicone or foam gaskets to isolate the plate from the case, aiming to provide a softer, more flexible typing feel and reduce typing noise.

The AULA F75 Max vendor description states it comes with factory-lubed LEOBOG Reaper linear switches. These are 5-pin switches with a 45g actuation force and a POM stem.

Yes, the Redragon product description mentions 'Pro Software Supported' for creating macros, custom keybindings, and lighting effects. The AULA F75 Max also supports software for key remapping and screen customization.

Both keyboards have sound-dampening features. The Redragon emphasizes a '5-Layer Noise Dampening' system with specific foams. The AULA uses a layered foam and pad system and pre-lubed switches for a 'creamy, thocky' sound. Without direct sound tests, both are designed to be quieter than non-dampened boards, but the Redragon's marketing places more emphasis on its multi-layer approach.
