Overview
The HealthSmart 18-220-000 is a battery-powered digital thermometer with an LCD display, weighing about 0.2 pounds, built for basic body temperature readings.
Category and title agree here, this is a genuine thermometer rather than a mislabeled supplement listing. The spec set is thin, an LCD display, battery power and a listed weight, but no probe type, reading time or measurement range is given, so those details are left out of this summary.

Performance notes
The 18-220-000 runs on batteries and shows readings on an LCD screen, weighing roughly 0.2 pounds, light enough for easy handheld use. Beyond display type and power source, the listing does not specify probe design, reading time or accuracy range, so those factors remain unconfirmed.
