What to know before buying

Listing details to confirm

The listing gives dimensions as “17L x 6.5W x 22H centimetres” in one field and “17 x 6.5 x 22 cm; 1 kg” in another, so the exact dimension format is inconsistent. Heat and cold level temperatures, 20 speeds, seven heads, the pressure display, USB-C and the carrying case are listing claims rather than independently confirmed specifications. The listing advises charging for approximately 6 hours on receipt.
