Optimus H-5210 Infra-Red Electric Compact Heater

Pros: Hot heat fast
Cheap
Uses less energy than other space heaters
Cons: Doesn't oscillate
Quirky control knob
One color choice

The Spuds have had and still have their share of space heaters of multiple brands and of variable quality and efficiency. I decided that we should have one on the screened porch for the occasional brief periods that Mrs. Spudman goes out there to sit. ...

Pros: Small, efficient, quiet, safe, positive reviews
Cons: None yet

This little item was too good to be left without a review so here goes... I have owned dozens of heaters throughout my half century of living. From electric fan heaters to oil filled convection heaters to other quartz heaters and on and on. ...

Pros: Quiet and more reliable due to simplicity.
Cons: Slightly lower heat output (800 watts Vs 1200 watts on the larger units).

I purchased two of these after my two other quartz heaters failed. The advantage this unit has over others is simplicity. There are no fans and no complex circuitry to ultimately fail. The units are dead quiet. They do not throw as much heat as the larger Holmes units but are satisfactory for most intended uses. There are two choices of heat output, 800 watts or 400 watts.
