The situation where a device meant to display the quantity of tetrahydrocannabinol (THC) oil remaining within a cartridge or container malfunctions or is unreadable presents challenges for users. An example includes a vape pen where the window or electronic display designed to show the oil level is obscured, broken, or providing inaccurate information. This prevents the user from accurately gauging how much oil is left.
Accurate assessment of the remaining consumable is important for several reasons, including managing consumption, avoiding unexpected depletion, and ensuring consistent dosages. Historically, users have relied on visual cues and subjective estimations, leading to inaccuracies. Modern devices often incorporate visual indicators to address this issue; however, malfunctions defeat the purpose. This impacts consumer experience and creates uncertainty about product usage.
