Compact Silent Keyboard

The BFKK wireless keyboard has 90 round silent keys in a slim black frame. A 2.4 GHz link gives up to 20 metres or 66 feet of range with 360 degree coverage. The 250 Hz return rate keeps transmission stable and smooth. Two included batteries power the unit.

Multi-Device Users and Quiet Environments

It suits anyone who switches between three paired devices such as a phone, laptop and PC. The silent micro-switch design cuts noise by about 95 percent for shared spaces. Buyers who want more storage or a full-size layout with a numeric pad should look elsewhere.

90 Silent Keys and 250 Hz Return Rate

The 90-key layout with round caps reduces wrong input and keeps the board portable. A 250 Hz return rate ensures smooth transmission without delay or frame skip. This combination decides whether the keyboard fits your typing and switching needs.
