Let me start by saying this CLEVAST heater is a BEAST in winter. That 2-second PTC heating? Legit. I tested it in my drafty home office (RIP energy bills), and within minutes, it transformed my typing-numb-fingers zone into a toasty cocoon. The 83° oscillation is smooth—no jerky robot movements—and actually distributes heat beyond "direct blast radius."

Smart Features That Shine: The app control saved me during a Netflix binge—realized I left it on upstairs while snuggled under blankets. Alexa integration worked flawlessly ("Alexa, melt my icicle toes"). RGB night light? Surprisingly useful for midnight snack runs without blinding myself.

But Here's the Tea: That "43dB quiet" claim? More like a white noise machine on high setting—fine for daytime but noticeable during Zoom calls. The ECO mode is genius (cut my usage by ~30%), though it struggles in large spaces beyond 150 sq ft. And yes, the physical power switch placement is weirdly Jurassic—almost missed it behind the unit.

Safety Wins: As a paranoid pet owner, the tip-over shutoff gave me peace of mind when my cat attempted heater parkour. ETL certification = no sketchy sparking noises.

Final Verdict: At $120-ish, it's pricier than basic heaters but justifies cost with smart features and rapid heating. Just don't expect whole-house warmth—it's a *space* heater, not a furnace replacement. Ideal for bedrooms/home offices where you want control without leaving your blanket fortress.
