So high-tech it makes you bleed!
Here a review: I bought this scraper for my grandson for Christmas. The first one didn’t work at all but the seller sent me a new one with no problems. My grandson likes the scraper, although we’ve had a very mild winter this year & he hasn’t used it very much. It heats up & melts the ice . The only problem is that it must be plugged into your car lighter socket and you have to keep the door or window ajar in order that you don’t cut the cord.
