Redragon COVE K733 vs OTIIM K729: your questions
No, the COVE K733 is not a full keyboard. It is a 22-key mechanical numpad, designed as a supplementary device for users who have a keyboard without a number pad, such as a 60% or TKL layout.
No, the OTIIM K729 is a wired-only keyboard. It connects via a detachable USB Type-C cable. The COVE K733 is the model that offers wireless connectivity through Bluetooth and 2.4 GHz.
For gaming, the COVE K733 has a technical advantage with its 8000 Hz polling rate, which can offer lower latency. However, the OTIIM K729 is a dedicated TKL keyboard that Redragon markets as 'dedicated for FPS gamers' for its space-saving layout. The best choice depends on if you need a macro pad (K733) or a full gaming keyboard (K729).
Yes, both the Redragon COVE K733 and OTIIM K729 feature hot-swappable sockets. The K733 product description specifically mentions a '99.8%+ switches compatible free-mod hot swappable' design.
The COVE K733 has a built-in calculator display and a dedicated calculator mode. However, some customer reviews on the vendor page indicate the calculator may not follow standard operator precedence (e.g., 2+3*4=20 instead of 14), which is a potential limitation for complex calculations.
The OTIIM K729 uses mix-color PBT keycaps. PBT plastic is generally more resistant to shine and wear compared to ABS keycaps. The keyboard also features south-facing RGB lighting.
The COVE K733 is far more portable. It weighs only 230g and measures 98 x 165 x 38 mm, compared to the OTIIM K729's 880g weight and larger 80% form factor. The K733's wireless functionality also enhances its portability.
The OTIIM K729 listing mentions 'Pro Software Supported' for creating macros and lighting effects. The COVE K733 vendor page has a 'Software Download' section, but the specific capabilities for the numpad are not detailed in the provided information.
Both keyboards come with Redragon's Custom Dragon Chant Switches, which are described as thick-lubed linear switches. The product descriptions for both mention a 'creamy' and 'cozy' typing feel.
According to the vendor listing, the OTIIM K729 package includes the keyboard, a detachable USB Type-C cable, a keycap and switch puller, four spare switches, a user manual, and a Redragon sticker.
Both keyboards feature a gasket mount design and a five-layer noise dampening system. Redragon's description lists components like 3.5mm PO foam, IXPE switch foam, a PET sound pad, and silicone pads for both models, which aim to reduce hollow noise and create a dampened acoustic profile.
The OTIIM K729 is better suited as a primary keyboard for programming due to its complete 87-key TKL layout, which includes all alphanumeric keys, modifiers, and arrow keys necessary for coding. The COVE K733 is only a numpad and cannot function as a standalone typing keyboard.
