I've been using the Comfort Zone CZ45E heater for a few weeks now, and it's been a mixed bag of cozy warmth and minor frustrations. Let me break it down for you.

The Good: This little powerhouse heats up my home office (about 120 sq ft) in under 10 minutes. The adjustable thermostat is genius - it cycles on/off to maintain temperature, which I've noticed does help with energy bills. The safety features (tip-over switch and overheat protection) give me peace of mind around my curious cat.

Real-World Use: I keep mine under my standing desk, and the directional heating is perfect - no more freezing feet while working! The fan-only mode surprised me with how strong the airflow is for summer use.

The Not-So-Good: Like some reviewers mentioned, quality control seems inconsistent. My first unit had a loose tip-over switch that needed adjusting. Also, the plug does get VERY hot after prolonged use - I now always unplug it directly from the wall (not by pulling the cord).

Pro Tip: Don't use an extension cord with this. At 1500W, it needs to be plugged directly into a wall outlet to avoid overheating issues.

Final Verdict: When you get a good unit (which seems to be about 75% of the time), this is an excellent space heater for small rooms. Just test it thoroughly during the return window.
