Top complaints
Lasko FH500 DUO Comfort Tower Fan & Space Heater
- Keeps shutting off or stops working
Reliability is a negative aspect in Amazon's review summary, with multiple owners saying it keeps turning off and stops working after a short period of use.
- Display too bright, remote hit or miss
Brightness is a negative aspect on Amazon, with several owners finding the LED display annoyingly bright; opinions on the remote are split.
- Confusing icons, bulky, filter to vacuum
Tom's Guide needed the manual to decode the icon controls, found the 41.9-inch, 12.5 lb tower awkward to carry, and notes a permanent filter that should be vacuumed every two weeks. Assembly takes about 15 minutes with a screwdriver.

De'Longhi Dragon Digital Full Room Radiant Oil-Filled Radiator
- Very slow to warm up
Wirecutter says it can take a half-hour or more before you feel any warmth, and even after an hour it might raise the room by only a few degrees.
Source: Wirecutter - Burning or chemical smell
Odor is a mixed aspect on Amazon, with some owners reporting a burning chemical smell. Wirecutter says new oil-filled radiators can give off a stench from leftover manufacturing oil that should fade.
- Hot surfaces, bulky, some early failures
Wirecutter measured the case at 180°F after four hours, hot enough to burn skin, and notes it weighs 25 lb, is suitcase-sized and can be top-heavy. Reliability is mixed on Amazon, with some owners saying it stopped working after two weeks. The warranty is just one year (Wirecutter).
