Overview

• Multiple users, including at least two corroborated cases and a prominent Reddit account, found their complimentary bottles melted or distorted after leaving them in parked vehicles during the recent heat wave.
• The bottles are made from 100% recycled PET plastic, which experts say begins to soften and deform at temperatures above 140°F commonly reached in car interiors.
• Health specialists warn that extreme heat can trigger chemical breakdown in PET and recommend discarding any liquid stored in bottles that have been exposed to high temperatures.
• Availability remains constrained by shipping delays, with the promotional giveaway limited to select T-Mobile stores after a postponed launch.
• T-Mobile has yet to issue any official statements or safety advisories addressing the heat sensitivity and potential risks of its promotional water bottles.
