What to know before buying

Listing details to confirm

Listing details conflict on dimensions: one entry says 25D x 25W x 13H millimeters, while another says 12.09 x 6.25 x 2.18 cm; 68 g. The claimed 40-hour runtime is tied to low mode in one description, while charging time is stated as both 45 minutes and 35 minutes. Mode counts also differ: five modes in one feature description, Low/High/Strobe in another, and six modes in promotional panel text. Confirm the selected listing's dimensions, operating modes and charge/runtime claims before buying.
