Onbest 3-in-1 Ceramic Fan Heater: what works, what doesn't?
What works well
- 3-in-1 use: cold-air fan plus two heat settings, usable in summer as well as winter
- Very compact & light: 16 × 15 × 10 cm at 0.8 kg with a carry handle, fits under any desk
- Fast PTC warmth: ceramic element heats up precisely, thermostat holds the temperature
- Basic safety: tip-over and overheating protection as well as rubberised feet as standard
- Cheap way in: under €20 for an extra heater with fan function
Points of criticism
- Spot heating only: 1,500 W warms the immediate surroundings, the device is too small for whole rooms
- No-name brand: with Onbest, warranty and spare parts support are hard to judge
- Not completely silent: audible as a fan heater, no oil radiator replacement for very noise-sensitive environments
