These are a really good idea as last winter I wasted a lot of time de-misting the car because it was so damp inside. I bought two of these (one for a relative) and they instantly solved the problem so I was delighted. I do however find it very difficult to recharge them in the microwave. If I follow the instructions two-three times then I can get most of the beads back to a lightish shade of orange, but the bag doesn't seem to let the heat and damp out effectively, so by the time they’ve cooled down the beads have re-absorbed the moisture and turned white again.

Seems to work pretty well... But the only problem is the beads don't go back to orange, so you're not totally sure when it's ready to go be reheated / or go back to the car. If this issue could be sorted out, then it should probably score higher.

My husband's car sits outside and in the winter gets very damp inside due to condensation. This dehumidifier save time and effort clearing condensation off the windscreen as it works very well.

It does work like in the description , soaking humidity . To restore just inserte in the microwe. A little gem

I use these on the dash board of my car in the winter to help keep the Misty windows clearer. I’ve had one for about three years. It still works and still refreshes after microwaving. I think it is now beginning to be less effective so I bought another one to use with it
