Update:Used it again today in the car as it is starting to get cooler outside. Don't know if I was using it wrong the first time, but it seems to be much warmer. There is 1 indicator for the heat level and timer setting, meaning you have to toggle the heat to the High setting and then toggle the timer. Would be better if there were 2 separate indicators for heat and time, but still better.Very soft, but light weight. If you're looking for something heavy or even just mid weight, this probably won't do. On the HIGH setting, it gets just somewhat warm. Didn't even bother with the MID or LOW setting. Don't think it would be really useful in a setting where it's really cold and you're trying to get warm. I tested it inside using an AC adapter on a warm summer day and could barely feel any heat. So, I'll test it out again in my car when it does actually start to get cold outside, but I don't think it'll make a difference. The timer works just fine and, as I noted earlier, it is very soft, hence the 2 stars.
