AULA F75 vs Redragon UCAL MAX K673: your questions
The AULA F75 has a hybrid plastic and aluminum case, while the Redragon UCAL MAX K673 uses a plastic case. The AULA's inclusion of metal typically contributes to a more solid and premium feel. The AULA listing also details a more complex internal construction with multiple foam and padding layers.
The Redragon K673 lacks specific gaming-oriented specifications like a stated polling rate or features such as Rapid Trigger, which are listed for the AULA F75. While it is a mechanical keyboard with linear switches, the AULA F75 provides more verifiable data for gaming performance, including a 1000 Hz polling rate.
Yes, both the AULA F75 and Redragon UCAL MAX K673 feature hot-swappable sockets. The Redragon vendor page specifies its socket is compatible with nearly all 3-pin and 5-pin switches.
Both keyboards are equipped with a 4000mAh rechargeable lithium battery. Actual battery life will depend on usage patterns and RGB lighting settings. Neither listing provides an estimated hours-of-use runtime.
The AULA F75 lists Mac/Win support in its extra features. However, its downloadable software is noted to support Windows systems only, so advanced customization may be limited on macOS.
The AULA F75 is the stronger candidate for quiet typing. It offers silent switch options and its vendor description details a five-layer sound-dampening system including Poron foam and a silicone pad. The Redragon K673 lists sound absorbing pads but does not specify silent switches.
The AULA F75 uses Cherry-profile double-shot PBT keycaps. The Redragon UCAL MAX K673 uses OEM-profile PBT keycaps with glowing letters. Cherry profile is typically lower than OEM profile.
Yes, both keyboards support software for customization. The AULA F75 has downloadable software for Windows. The Redragon K673 vendor page mentions 'Pro Software Supported' for creating macros and effects.
According to its vendor page, the Redragon UCAL MAX K673 package includes the keyboard, a detachable USB Type-C cable, a keycap & switch puller, a nano receiver, four spare switches, a user manual, and a sticker.
Both keyboards use a gasket mount structure. The Redragon vendor description calls it 'Redragon Gasket Out,' using precision-locked covers with gaskets for noise reduction and flexibility. The AULA description states it uses a gasket structure but does not give it a specific name.
The AULA F75 vendor description states it features 'factory-lubricated mechanical switches.' The Redragon K673 listing does not mention pre-lubrication for its included Mint Mambo linear switches.
Portability is close. Both are 75% layouts. The Redragon K673 lists dimensions of 37 x 335 x 37 mm, while the AULA F75 is 43 x 143 x 323 mm. The Redragon's listed profile is thinner, but it is also heavier at 1200g versus the AULA's 1023g.
