In terms of portability, it includes strong casters and a handle which make moving it between rooms straightforward despite its fairly heavy weight (around 17 pounds). The size is compact enough to fit in most spaces without being intrusive.

Manual controls are straightforward to use. Measuring 13.19 x 9.84 x 26.38 inches, it is compact enough for most indoor spaces.

Its upgraded M-shaped fins improve heat spread efficiently, creating a warm, cozy environment without drying the air. You can pick from three heat levels (600W, 900W, 1500W) and set the thermostat precisely between 41°F and 95°F, which helps maintain a comfortable temperature while saving energy.

This heater operates almost silently since it doesn't use a fan, so it’s well-suited for quiet environments like bedrooms or study rooms. Portability is decent—while it weighs about 23 pounds, it has wheels and handles for easy moving between rooms. Safety features are thoughtfully designed: it automatically shuts off if it tips over or overheats, and the flame-retardant materials add peace of mind for families.

The size is somewhat large (about 15 by 11 inches footprint and 26 inches tall), which might be bulky for very small spaces. Also, while the timer and remote control add convenience, some users may find the weight a bit heavy if they plan to move it frequently without rolling it. Noise is minimal, but the lack of a fan means it relies solely on radiant heat, so warming a very large or drafty area might take longer compared to fan heaters. This PELONIS heater is a quiet, safe, and energy-conscious option mainly suited for medium-sized indoor rooms where steady, dry heat is preferred without background noise.
