(checked 2026-10-10)Small sample: only 47 ratings (1-star 6%, 2-star 10%).
A magnetic pair with a screen and 72 heat steps (104 to 140 °F) that heats quickly and syncs both halves. CNN Underscored liked the control and grip. It weighs just under a pound, about twice the Ocoopa UT2, its small black buttons are hard to use, and nearly 1 in 6 of its few Amazon ratings are 1 or 2 stars.
Top complaints
- Heavy
The pair weighs just under a pound, nearly twice CNN's top pick, which kept it out of CNN's winners.
Source: CNN Underscored - Buttons are hard to see and use
Everything but the logo is black, so the small plus and minus buttons are hard to see. CNN often switched to Celsius or turned on the flashlight (and its strobe) by accident.

Amazon's summary says heat gets mixed feedback, with some owners noting they get really hot on the highest settings.
What owners love
- Precise, quick heat
It has 72 levels in half-degree steps from 104 to 140 °F and a screen showing the real-time temperature. It heated up quickly, and both halves sync when joined (CNN).
