Let me start by saying I've used this exact thermostat model since 2007 - that's over 15 years of daily use! When my old unit started giving false temperature readings, I immediately replaced it with this same model because I know its reliability firsthand.

The backlight is a massive improvement over previous versions. While it only activates when touching specific icons (wish it worked with any screen touch), the brightness is now so strong it could practically double as a nightlight! Some might find it too bright, but for us older folks with fading eyesight, it's perfect.

Programming is surprisingly intuitive if you follow the logical steps. I've set up six of these at our church recently, and they've already cut our utility bills significantly. The password protection feature is genius - you can lock the schedule while still allowing temporary temperature adjustments without compromising your settings.

The installation had one tricky moment: separating the body from the base isn't as obvious as it should be. Pro tip: look closely - it snaps apart without screws or force. This tripped me up on my first install years ago.

Accuracy is spot-on in my experience, though some reviews mention calibration issues. Mine has maintained precise readings for years. One user reported saving $600 on their gas bill after switching to this thermostat - and after seeing my own energy savings, I completely believe it!

A few drawbacks: The packaging from some sellers can be questionable (mine arrived bouncing around in an empty box). Also, while programming isn't rocket science, first-time users might need to consult the online manual. And yes, refurbished units seem to have higher failure rates based on reviews.

Bottom line? For a reliable, energy-saving thermostat that doesn't require WiFi or complicated apps, this remains my top choice after 15+ years of use across multiple properties.
