What to know before buying

Listing details to confirm

Bluetooth version claims are inconsistent: the hardware interface lists Bluetooth 4.0, while other product details claim Bluetooth 5.3 and compatibility with Bluetooth 5.4 or below. Dimensions are also contradictory, listed as 5L x 5W x 2.4H centimetres and 50 x 50 x 24 cm; confirm these details for the selected listing. The stated 10-12 metre (30-40 feet) range is for open space, and the listing warns that wireless interference can affect reception.
