Rii Bluetooth Keyboard X9 Wireless Bluetooth Keyboard with RGB Backlit

In this review of the Rii Bluetooth Keyboard X9 the bottom line is straightforward: this is a travel-friendly, rechargeable Bluetooth keyboard for tablet and laptop users who want a slim aluminium case, quiet typing and basic RGB backlighting. The reviewer found it best for someone who types on an iPad, Surface or Android tablet and needs a compact, durable keyboard to carry between meetings. The single biggest reason to buy is the combination of a lightweight aluminium alloy shell and a low profile scissor key mechanism that keeps typing comfortable during long sessions.

Key Features

• Slim aluminium case: The lightweight aluminium alloy body makes the keyboard easy to pack for travel or business trips without adding bulk.
• Bluetooth 5.0 connectivity: Reliable wireless pairing with iOS, Android, Mac OS and Windows devices provides broad compatibility across tablets, phones and PCs.
• RGB backlit keys: Three-color LED backlights (red, blue, green) give visual clarity in low light and a simple aesthetic boost when typing.
• Rechargeable battery: The internal battery is designed to last about 22 days with 8 hours of daily use and enters sleep after 30 minutes to conserve power.
• Low profile scissor keys: Quiet, stable keys improve feedback and reduce finger fatigue during prolonged typing compared with typical membrane laptop keys.

Who It's For

The Rii X9 suits students, remote workers and frequent travelers who use an iPad 10th, iPad Pro, iPad Mini, iPad Air, Surface, Android tablet or a laptop and want a portable Bluetooth keyboard that feels more stable than a thin folio keyboard. Its aluminium case and quiet keys are especially helpful for people who type in shared spaces and need a device that is discreet.

It is less appropriate for users who need a full-size desktop mechanical keyboard, advanced programmable keys, or multi-zone RGB effects; it also lacks an integrated trackpad or case docking solution, so buyers who require those features should look at keyboard-cases or premium peripherals instead.

Pros & Cons

Pros

• Solid aluminium alloy build keeps the keyboard slim yet durable for travel.
• Quiet low profile scissor keys offer comfortable, stable typing and reduce noise.
• Broad Bluetooth 5.0 compatibility works with iOS, Android, Mac OS and Windows devices.
• Rechargeable battery with automatic sleep helps extend runtime between charges.

Cons

• RGB lighting is limited to three simple colors and lacks per-key customization.
• No integrated case or trackpad, so additional protective accessories may be needed for tablet users.
