Tumbler Testing

At BenderBilt, we are committed to providing high-quality products that perform just as well as top name brands—without the premium price tag. We believe that great performance and value should go hand in hand, which is why we carefully test and compare our products to industry-leading brands. Our goal is to ensure that our customers receive the best possible quality at a more affordable price. This test demonstrates how our off-brand tumbler matches the performance of a well-known competitor, proving that you don’t have to overpay for excellence.

 

Data Comparison:

Testing Process:

Two 30 oz stainless steel insulated tumblers were tested—one Yeti-branded and one off-brand cup intended for business use. Both cups were placed on Styrofoam to prevent heat transfer from the counter. The ambient room temperature was 72°F for most of the test, except for a reduction to 70°F at 1:55 AM.

Each cup started at an ambient temperature of 75.2°F. The test involved filling each cup with 132g of ice and 292g of water (initially at 69.8°F). After mixing the contents for 10 seconds, temperature readings were recorded at regular intervals using an IR temperature laser and a thermal camera. The test continued until 10:15 AM the following day.

Summary of Results:

  • Both cups demonstrated nearly identical internal and external temperature retention over time.
  • Initially, the internal temperatures of both cups were around 35°F.
  • Over approximately seven hours, the internal temperatures remained within a narrow range of 34.5°F to 36.3°F.
  • Ice in both cups fully melted by 1:55 AM.
  • After ice melted, the internal temperatures gradually rose, reaching around 55°F by 10:15 AM.
  • The external temperatures of both cups followed a similar trend, staying within a small variation range.

Conclusion:

The data shows that the off-brand cup performs on par with the Yeti cup in terms of thermal retention. Both cups maintained low internal temperatures for an extended period and exhibited similar external heat resistance. This suggests that the off-brand cup is a reliable alternative at likely a more competitive price point.
