Combos

Yes. Combos with Bluetooth support (e.g., SKM64-2, SKM64-3, COE401) can connect to iPads, Android tablets, and smartphones. Some models also allow switching between three devices.

It depends on the model. Dry‑battery combos (e.g., COE200) can last up to 365 days standby. Rechargeable models (e.g., SK38-3, COE401) offer 1‑2 months of typical use per charge, with some featuring fast USB‑C charging.

Most of our keyboards are not fully spill‑proof, but some models (e.g., COE200) feature a spill‑resistant design. We recommend keeping drinks away from the desk.

In most cases, the combo is sold as a set. However, we offer replacement receivers and some accessories. Please check our Accessories page or contact support.

No. All SEENDA combos are plug‑and‑play on Windows, macOS, Chrome OS, and most Linux distributions. No extra software required.

2.4G uses a tiny USB receiver (included) – it's very stable and has near‑zero lag, ideal for gaming. Bluetooth connects directly without occupying a USB port, but may have slightly higher latency. Many of our combos support both.

Use a soft, slightly damp cloth to wipe the surface. For keys, use compressed air. Do not immerse in water or use harsh chemicals.

Yes. Most combos work with Mac via Bluetooth (e.g., SKM64-2, SKM64-3, COE401). The COS500 combo is specifically designed for Mac with a dedicated Apple layout. For 2.4G USB mode, some combos are Windows‑only – check the product details.
