For $12.14 I think this is a great little heater. It will not give you a blast furnace rush of heat like some seem to expect, as if it would replace your cars heater core. If you want that kind of heat then spend the big bucks and have it fixed. I can't afford to, so I plan on getting 2 of these since my heater core is on the blink in my truck. For poor folk like me its a bargain!

Plug in for instant heat! It has just a fan or both fan and heat. Defrosts quickly and takes the chill out of the old VW Pop Top Camper quickly. It is also pretty quiet. Mounting bracket it simple. Great For what I need it for.

It certainly warms my van without the engine being warm like it advertises and in ten minutes...Just give it a chance to work for you..it did great when the Bay Area in Northern California dipped in temperature just this last winter...it does everything it says it does and just one bad review of this product did not stop me..give it a chance...the vendor(do not know the vendor name} is FAST and reliable-it came in less than a week...

Although small and not having high heat output, provides good backup for the money. Can assist for Rear Window Defroster when placed close to glass. -I used 2 units, one on each side, for backup heat. Small size makes installation location easy; Fused, low power drain allows for continous use.

The heater is not very powerful. It only defrosted a small 8" - 10" circle on the windshield. It does knock off the chill inside the vehicle, but does not warm it by any means.
