What to know before buying

Listing details to confirm

Listing details are inconsistent: the connectivity field says “Wi-Fi,” while feature text specifies 2.4 GHz wireless and USB. Battery capacity is described as both 2000mAh and 2200mAh, and the scan-rate field says “200 seconds,” which does not clearly establish a scanning speed. Confirm the exact selected variant and these details before buying.
