What to know before buying

- The listing gives a two-hour battery life and three-hour charging time, but does not specify the operating mode or conditions for those figures.
Listing details to confirm
Listing details are inconsistent: the form-factor field says “Wrap Around Neck Massager” although the product is presented as a knee massager, and listed dimensions use different formats. The page also describes the screen as both LCD and LED, and battery details say “Nonstandard Battery” without identifying its type. Confirm the selected listing’s configuration before purchase.
