### ⭐⭐⭐⭐⭐ Works great

Works great seems to be the exact same thermostat you pay way more for from certain brands.

### ⭐⭐⭐⭐⭐ Pleasantly surprised
*by F***D on November 24, 2025*

Seems to be a perfect replacement for the OEM. Actually, the software functionality seems to be a step up - likely because it was a 2024 year of manufacture versus a 2017 on my original OEM thermostat. Very pleased with this OJ Microline version.
