Let me start by saying I had high hopes for this gadget. The idea of melting snow off my car without lifting a finger sounded like magic. But reality hit hard.

First morning trying it: -10°C outside. Fully charged both units, placed them on my dashboard as instructed. Came back 30 minutes later... still a winter wonderland on my windshield. Had to scrape manually anyway.

The biggest flaw? You have to physically go to your car to turn it on. At that point, I might as well just start scraping. For Alaskan winters where I need my car pre-warmed, this defeats the whole purpose.

I did notice some effect on very light frost - but anything substantial? Forget about it. My neighbor's identical unit actually worked once (lucky him), while mine just sat there like expensive paperweights.

Final verdict? Save your money. Unless you enjoy paying premium prices for what might essentially be fancy decoy alarms (yes, I saw those listings too). Stick to remote starters and good old-fashioned scrapers.
