### ⭐ False specs in title - does NOT have 500c range.
*by A***L on August 15, 2025*

max Temp. range 120c - not 500c as listed. scammed.

### ⭐⭐⭐⭐ Doesn't Come with Instrcutions
*by J***O on October 29, 2024*

Turns out is is a great little unit. Even better than expected. It has all kinds of great features and it does work perfectly. The issue is that there are no instructions. None on amazon, and none with the unit. After spending some time searching other thermostats on amazon that looked the same i was able to locate instructions from a different seller. Other than that, I am Pleased. In case anyone's looking here they are.
