Desktop looks like a plate of spaghetti?  

Bought a slick wireless mouse on Double-11 only to discover your tower was born before Bluetooth was a thing?  

Slide a 5 $ stick into any USB-A port and turn the PC into a cable-free command center.

Why version matters  

• BT 5.0 → fine for headphones, laggy for Fortnite.  
• BT 5.4 → 2 Mbit/s EDR, 500 kb/s LE, < 1 ms latency, twenty-metre range through drywall.  

Rule: always buy the highest version; it still speaks every older accent.

COMFAST BT-54 family (both run BT 5.4, driver-free on Win 10/11, macOS, Android-x86)

1. Nano-hideaway CF-BT54N  

• 1.8 cm stub—insert once, forget forever.  
• Perfect for laptop road-warriors who need mouse + AirPods on the plane.

2. High-gain CF-BT54A (3 dBi antenna)  

• Magnet base on 80 cm extension—stick to PC case, aim toward couch.
