Let me start by saying this little heater PACKS a punch! I've been using it in my home office (about 120 sq ft) and it warms up the space surprisingly fast. The 1500W setting gets almost uncomfortably hot within 15 minutes - I actually have to dial it down to the 950W energy-saving mode most of the time.
The safety features give me peace of mind. When my cat accidentally knocked it over (oops!), the tilt-shutoff worked perfectly. No melted carpets or panicked cat-chasing scenes here!
Now for the quirks - that knob control? Not as precise as digital buttons. Sometimes I overshoot my desired temperature and have to fiddle with it. And while they advertise 'whisper-quiet,' there's definitely a noticeable fan hum at higher settings. Not deal-breaking, but don't expect complete silence.
Portability is where this shines. At just over a foot tall, I move it from my home office to bedroom easily. The cord could be longer though - had to rearrange furniture to reach certain outlets.
After 3 months of daily use (including one replacement after initial unit stopped heating), here's my verdict: Great for small spaces if you can overlook minor interface issues. Just buy from a seller with good warranty support!
