Review on 🔥 Portable Infrared Space Heater for Indoor Use – Radiant Quartz Heater with 2 Heat Settings, Instant Warm-up, Silent Operation; Perfect for Home Office, Bedroom. Includes Overheat & Tip-Over Protection. by Emily Wilson

I like this heater because it's the first heater I've ever seen with 100% ROPS. Most heaters skimp on safety features, and poor quality means they can be knocked over but still turn on. It has a simple button on the bottom of the heater and if the button is not pressed (heater is placed on a flat surface) it will turn off. on or both bands on. The control knob has two settings to turn off, two settings to turn on the top bar, and two settings to turn on the bottom bar. I'm not sure what's going on here. I suspect it's the same controller for a more expensive model with more settings and they just put three different options on the controller twice. This is a tiny 500w heater. I'm not sure I would call it a space heater, but it's good under the table in low temperatures.
