What to know before buying
Listing details to confirm
Bluetooth version details are inconsistent: the title and feature text claim Bluetooth 5.4, but the hardware-interface field says Bluetooth 5. The stated data transfer rate of 2480 MHz is also unusual as a rate specification, so confirm both details if they affect your purchase. The supported-OS feature list omits Windows 8.1 while the highlighted compatibility claim includes it.

Customer feedback highlights ease of use, compactness, connectivity and range, with reports of quick pairing and connecting multiple Bluetooth devices to a desktop. Some customers also describe improved speed and signal, but those reports do not establish a Bluetooth transfer rate, and a mention of a 5G signal does not show that this Bluetooth adapter provides cellular or Wi-Fi 5G. Driver compatibility experiences are mixed, which matters when matching the adapter to a Windows PC.
Positive themes
- Customers describe the adapter as easy to use and compact.
- Feedback reports good connectivity, signal and range.
Mixed feedback
- Driver compatibility receives mixed feedback.
